# What does the number with E mean? [duplicate]

When I do some computation, I get a number as follows. I cannot use this in my further computations as it requires it to be a number and not to have characters in between. How can I expand this number to an actual number?

2.725808E8

E or e, from Exponent Notation, is the scientific notation for powers of $10$ and can be replaced with *10^. So $$2.725808\mathrm{E}8 = 2.725808\times10^8.$$
