`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
