What is the meaning of E10 in calculator?
E10 means move the decimal to the right 10 places. If the number 1-9 is a whole number, then the decimal may not be seen, but for the purposes of moving the decimal, there is an invisible decimal after each whole number.
What is E+ in a number?
The Scientific format displays a number in exponential notation, replacing part of the number with E+n, in which E (exponent) multiplies the preceding number by 10 to the nth power. For example, a 2-decimal scientific format displays 12345678901 as 1.23E+10, which is 1.23 times 10 to the 10th power.
What does 3e 11 mean?

What is the mantissa before the E?
Strictly speaking, the mantissa (number before the E) must be greater or equal to 1 and less than 10 (or can also be said 1 <= x < 10 where x is the mantissa) and the exponent (number after the E) can be any integer. Any other scientific notation should be converted to an equivalent number of this form to be normalized.
What does E11 mean in scientific notation?

When do you use the E notation in a calculator?
Many calculators use the 'E' notation when the answer doesn't fit in the display screen. They just put E11 or whatever at the end and use all remaining available positions for the coefficient or mantissa (4.999… in this case).
Why do we use the E key on a calculator?
Most scientific calculators devote a special key to Euler's number, because it is one of the most important irrational numbers in mathematics and enters into all kinds of scientific calculations. This is the "e" key. Press it, and Euler's number will appear in your display to the accuracy the display allows.
Is 1E10 a hexadecimal number?
1E10 could be a hexadecimal number (see Sergei Michailov’s answer), but could also be a number in scientific notation. In fact, that’s what I first thought of when I saw the number, even though as a computer scientist I am very familiar with hexadecimal.
What Is Scientific Notation?
Scientific notation makes these numbers easier to handle by expressing the 0's as a power of ten. Using this notation, the mass of the Earth becomes 5.97 × 10 24 kg, and the mass of a hydrogen atom becomes 1.67 × 10 -27 kg. Instead of numbers with long strings of zeros that are difficult to count and even more difficult to display on a small screen, you have more manageable decimal fractions and exponents of 10.
Why do calculators use lowercase?
To complicate matters, some calculator manufacturers use lowercase "e" to denote exponents, inviting confusion between scientific notation and Euler's number, ...
How to enter scientific notation on a calculator?
It's the EE key. To enter a number in scientific notation, first input the argument, then press the EE key and enter the exponent. For example, to enter the mass of the earth, key in 5.97, then press the EE key and enter 24. The display will read 5.97E24 (or 5.97e24). Note that the number will appear with all its zeroes if they fit on the screen. For example, if you key in 1.2 EE 5, the display will show 120,000.
What does E stand for in math?
On a calculator display, E (or e) stands for exponent of 10, and it's always followed by another number, which is the value of the exponent. For example, a calculator would show the number 25 trillion as either 2.5E13 or 2.5e13. In other words, E (or e) is a short form for scientific notation.

What is the symbol for X 10?
It would be confusing and it wouldn't fit on a small display. To avoid these problems, manufacturers created a symbol for "X 10." This symbol is either E or e , depending on the calculator. This letter is always followed by a number, which is the exponent to which 10 is raised.
Why do we use the E key on a calculator?
Most scientific calculators devote a special key to Euler's number, because it is one of the most important irrational numbers in mathematics and enters into all kinds of scientific calculations. This is the "e" key. Press it, and Euler's number will appear in your display to the accuracy the display allows.
Why not just write out the number?
Why not “just” write out the number? Scientific notation lets us very quickly compare numbers. Obviously 3120000 is smaller than 8714300 and bigger than 63865.479. Well, more obvious when we write 3.12e6 and 8.71e6 and 6.39e4. The last one has two less digits before the decimal (e4 instead of e6) so is much smaller, while the first two have the same number of digits before the decimal but one starts with 3 and the other with nearly 9. So the first is about a third the size of the second but two orders of magnitude (two extra digits, or nearly 100 times the value) greater than the third. And just imagine how to deal with the federal debt! A number like 21 trillion has 14 digits and won’t even fit on a calculator display. But 2.1e13 lets us at least work with the number even if we avoid working with the problem.
What is scientific notation?
That notation is a convenience for writing and comparing very large, or in this case very small numbers. It is the form calculators often use for what your math or science teacher called scientific notation, whereby you give the first non-zero digit, then tell which decimal place it falls in. So 3,120,000 has six digits after the initial “3” and can be written 3e6, or better yet, without rounding all those other valuable digits, 3.12e6. Your number, 1e-4, means the 1 is four digits the other way, so 1e-4 = 0.0001.
How many digits are in 123456789?
It has 11 digits display. So, the calculator will show 123456789. when it is multiplied by 1000, we get 1.23456789* (10^11) For My calculator (Casio fx-115MS). So the answer which you can get is
What does e4 mean?
To be completely accurate, the e-4 means multiply by 10^-4 or 1/10^4 or .ooo1. In fact it is because the -4 is an exponent on base 10 that the letter e was chosen. Two more examples: 5e3 = 5 x 10^3 = 5000 with three digits after the 5 (the decimal point went over 3 spaces) and 3.86e-5 = 3.86 x 10^-5 = 0.0000386 with the 3 in the fifth decimal place (decimal point went over 5 spaces).
What is the mantissa before the E?
Strictly speaking, the mantissa (number before the E) must be greater or equal to 1 and less than 10 (or can also be said 1 <= x < 10 where x is the mantissa) and the exponent (number after the E) can be any integer. Any other scientific notation should be converted to an equivalent number of this form to be normalized.
What is 1.5E10 / 2?
For example, 1.5E10 / 2 would be 0.75E10, but then converted to the equivalent 7.5E9 to be normalized.
What does the E stand for in a power?
So, the e actually stands for 10 and the number followed by it refer to the power of 10. In this case it is 10^11.
