What does DATA INF/1.D+300/ mean in Fortran?

Question

I\'m translating some Fortran to our C# app and I\'m trying to figure out what a bit of Fortran means at the top of a function.

  DOUBLE PRECISION INF, DMIN,         


        

Answer 1

The code is declaring a constant called INF (i.e. infinity) with the value 10^300. You would want to substitute double.PositiveInfinity or double.MaxValue.
