The  999e44  notation is intended to be similar to scientific notation, 
where 44 is the exponent, in base 10.

So redoing your equalities:

5e18 == 5*(10**18)
int(5e18) == int(5 * 10**18)
1.01325e5 == 1.01325 * 10**5

The extra parens in the first case, and the extra spaces in the others, are just for readability.  It'd be just as correct to say:
1.01325e5 == 1.01325*10**5
