var=1.e12
What is the meaning of this expression and its equivalent in FORTRAN 90/95

1I'd guess a variable named 'var' gets assigned a real value of 1.e12 (10^12) . I think it will also be Fortran 95 – Pieter21 Feb 07 '15 at 10:38

3This is not only valid Fortran 95, but valid almost any other language, including pocket calculators. – Vladimir F Героям слава Feb 07 '15 at 10:46

Elementary, my dear Watson:
1.e12 is a floating point numeral; in this case, it's value is 1.0 * 10^12.
its equivalent in fortran90
Um, I think that's valid f90.
