2.6) Dealing With Very Large And Small Numbers


You don’t want to be entering too many zeros so scientific notation is represented in the following way.

Number Scientific notation in Fortran
34567.34 3.456734E4 or 3.456734E+04

It is confusing since the E represents x10 to the power and not the e in math which is e = 2.7182818.

So in a Fortran code, if you had a variable a, you could set it equal to the number above by including a line as:

a=3.456734E4
