### 9.114 `FRACTION`

— Fractional part of the model representation

*Description*:`FRACTION(X)`

returns the fractional part of the model representation of`X`

.*Standard*:Fortran 90 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
