e is the scientific notation symbol.

In scientific notation, in order to make the formula simple, it can be expressed in the format with "E". For example, 1.03 times 10 raised to the 8th power can be abbreviated as "1.03E+08".

When expressed in this format, the number before E and the number after "E+" must be accurate to tenths (if there are not enough digits, add 0 at the end), for example, 7.8 times 10 raised to the 7th power, the normal writing method is : 7.8x10^7, abbreviated as "7.8E+07". Extended information

Usage of e:

Scientific notation is used because the number of digits displayed by the calculator is exceeded.

E is exponent, which means the exponent with base 10.

This format displays numbers in exponential notation, replacing part of the number with E+n, where E (for exponent) means multiplying the previous number by 10 raised to the nth power. For example, expressing 12345678901 in Scientific Notation format with 2 decimal places results in 1.23E+10, which is 1.23 times 10 raised to the 10th power.

6.25e+18=6.25*10^18
