8.90 FRACTION — Fractional part of the model representation

Description:
FRACTION(X) returns the fractional part of the model representation of X.
Standard:
Fortran 95 and later
Class:
Elemental function
Syntax:
Y = FRACTION(X)
Arguments:

X The type of the argument shall be a REAL.

Return value:
The return value is of the same type and kind as the argument. The fractional part of the model representation of X is returned; it is X * RADIX(X)**(-EXPONENT(X)).
Example:
          program test_fraction
            real :: x
            x = 178.1387e-4
            print *, fraction(x), x * radix(x)**(-exponent(x))
          end program test_fraction
