NAMEIEEE_REMAINDER - Returns the remainder of x divided by y
SYNOPSISIEEE_REMAINDER ([X=]x, [Y=]y)
IMPLEMENTATION
UNICOS/mk and IRIX systems
CRAY T90 systems that support IEEE floating-point arithmetic
STANDARDS
CF90 and MIPSpro 7 Fortran 90 compiler extension to Fortran 90
IEEE Standard for Binary Floating-point Arithmetic
DESCRIPTION
The IEEE_REMAINDER intrinsic function returns the remainder of the
operation x divided by y. Note that this function does not have
precisely the same definition as either of the Fortran 90 intrinsic
functions MOD(3M) or MODULO(3I).
The IEEE_REMAINDER function accepts the following arguments:
x Must be of type real. It can be scalar or an array.
y Must be of type real. If x is scalar, y can be scalar or an
array. If x is an array, y can be scalar or an array of the
same shape as x.
IEEE_REMAINDER is an elemental function. The name of this intrinsic
cannot be passed as an argument.
NOTES
The IEEE intrinsic procedures use the named constants contained in a
system module, so you must include one of the following statements in
your program:
* On UNICOS and UNICOS/mk systems: USE CRI_IEEE_DEFINITIONS
* On UNICOS, UNICOS/mk, and IRIX systems: USE FTN_IEEE_DEFINITIONS
The CRI_IEEE_DEFINITIONS module is obsolescent. It will be removed
for the CF90 4.0 release.
RETURN VALUES
The same type and kind type parameter as the argument of the largest
precision and range. For example, if x is type REAL(KIND=4) and y is
type REAL(KIND=8), the result is of type REAL(KIND=8). If either x or
y is an array, the result is an array of the same shape as one of the
array arguments.
The form of the result value is determined as follows:
* If x and y are both scalar, the result is a scalar.
* If x is an array and y is scalar, the result is an array in which
each element is the remainder of
x divided by y.
i
* If x is scalar and y is an array, the result is an array in which
each element is the remainder of x divided by
y .
i
* If x is an array and y is an array, the result is an array in which
each element is the remainder of
x divided by y .

EXAMPLES
REAL x, y, r
... ! Compute X and Y.
r = IEEE_REMAINDER(x, y)
IF (r /= 0.0) THEN
