NAME
FRACTION(3) - [MODEL_COMPONENTS] Fractional part of the model representation
SYNOPSIS
result = fraction(x)
elemental real(kind=KIND) function fraction(x)real(kind=KIND),intent(in) :: fraction
CHARACTERISTICS
o X is of type real o The result has the same characteristics as the argument.
DESCRIPTION
FRACTION(3) returns the fractional part of the model representation of X.
OPTIONS
o X : The value to interrogate
RESULT
The fractional part of the model representation of X is returned; it is X * RADIX(X)**(-EXPONENT(X)).
If X has the value zero, the result is zero.
If X is an IEEE NaN, the result is that NaN.
If X is an IEEE infinity, the result is an IEEE NaN.
EXAMPLES
