ifort functions for test NaN and Inf : Fortran
This is a discussion on ifort functions for test NaN and Inf within the Fortran forums in Programming Languages category; On Jul 18, 7:06 am, "ddb..." <ddb...> wrote: > Anybody knows an intrinsic function for testing if a variable is > -+INF.

Sorry if this is a duplicate, Google Groups isn't showing my reply, but it has been misbehaving the past few days. ifort provides the FP_CLASS intrinsic function (extension) for this purpose. Eventually we'll have the F2003 intrinsic module too. Steve...
