real_to_string Subroutine

public subroutine real_to_string(rval, real_fmt, compact_real, non_normals_to_null, str)

Convert a real value to a string.

Modified

  • Izaak Beekman : 02/24/2015 : added the compact option.
  • Jacob Williams : 10/27/2015 : added the star option.
  • Jacob Williams : 07/07/2019 : added null and ieee options.

Arguments

Type IntentOptional Attributes Name
real(kind=RK), intent(in) :: rval

real value.
character(kind=CDK, len=*), intent(in) :: real_fmt

format for real numbers
logical(kind=LK), intent(in) :: compact_real

compact the string so that it is displayed with fewer characters
logical(kind=LK), intent(in) :: non_normals_to_null

If True, NaN, Infinity, or -Infinity are returned as null. If False, the string value will be returned in quotes (e.g., “NaN”, “Infinity”, or “-Infinity” )
character(kind=CK, len=*), intent(out) :: str

rval converted to a string.
