8.119 FRACTION — Fractional part of the model representation

Synopsis:

Y = FRACTION(X)

Description:

FRACTION(X) returns the fractional part of the model representation of X.

Class:

Elemental function

Arguments:
XThe 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 * REAL(RADIX(X))**(-EXPONENT(X)).

Example:
program test_fraction
  implicit none
  real :: x
  x = 178.1387e-4
  print *, fraction(x), x * real(radix(x))**(-exponent(x))
end program test_fraction
Standard:

Fortran 90 and later
