E = 10^x
E is equal to ten to the power of whatever follows "E"

It means x10^, or "times 10 to the...power". So 4.0e-8 would mean 4.0 times 10 to the -8 power, which is 0.00000004. To express it in terms of 10^-7, divide the 4.0 by 10 and multiply the 10^(-8) by 10 (which means adding 1 to the exponent). The result is 0.4x10-7.

It's a way of saying "this is the exponent in scientific notation."
So 4.0e-8=4.0*10^(-8) or 0.4*10^(-7) or 0.04*10^(-6)...

the "e" means exponent of 10...
4.0056e25 means 4.0056x10^25...
4.0e-8 means 4.0x10^(-8)

The natural logarithm, formerly known as the hyperbolic logarithm, is the logarithm to the base e, where e is equal to 2.718281828459... (continuing infinitely). The natural logarithm can be defined for all positive real numbers x as the area under the curve y = 1/t from 1 to x, and can also be defined for non-zero complex numbers.

4.0 e -8 = 4.0 * 10^-8
e n
where as n is any value after the e, means 10^n

2E-05 = 2 * 10^(-5) = 0.00002
1.2E02 = 1.2 * 10^2 = 1.2 * 100 = 120
Get the picture ?
