NAME

MINEXPONENT(3) - [MODEL:NUMERIC] Minimum exponent of a real kind

SYNOPSIS

result = minexponent(x)

         elemental integer function minexponent(x)

          real(kind=**),intent(in) :: x

CHARACTERISTICS

o	X is a real scalar or array of any real kind
o	the result is a default integer scalar

DESCRIPTION

MINEXPONENT(3) returns the minimum exponent in the model of the type of X.

OPTIONS

o	X : A value used to select the kind of real to return a value for.

RESULT

The value returned is the maximum exponent for the kind of the value queried

EXAMPLES

Sample program:

    program demo_minexponent
    use, intrinsic :: iso_fortran_env, only : real32, real64, real128
    implicit none
    real(kind=real32) :: x
    real(kind=real64) :: y
        print *, minexponent(x), maxexponent(x)
        print *, minexponent(y), maxexponent(y)
    end program demo_minexponent

Expected Results:

      >     -125         128
      >    -1021        1024

STANDARD

Fortran 95
