NAMEMODULO - Modulo function
SYNOPSISMODULO ([A=]a, [P=]p)
IMPLEMENTATION
UNICOS, UNICOS/mk, and IRIX systems
STANDARDS
Fortran 90
DESCRIPTION
The MODULO function accepts the following arguments:
a Must be of type integer or real
p Must be of the same type and kind type parameter as a
MODULO is an elemental function. The name of this intrinsic cannot be
passed as an argument.
RETURN VALUES
The result type and type parameter are the same as a, which can be
integer or real.
When a is of type integer, if P = 0, MODULO (a, p) has the value r
such that A = Q x P + R, where q is an integer. The inequality
0 <= r < p holds if p > 0, and p < r <= 0 holds if p < 0.
If P = 0, the result is machine-specific. The result is not a
meaningful number (a NAN) when that value is available. Otherwise the
result is 0.
When a is of type real, if P = 0, the value of the result is A - FLOOR
(A / P) * P. If P = 0, the result is machine-specific.
EXAMPLES
MODULO(8, 5) has the value 3. MODULO(-8, 5) has the value 2.
MODULO(8, -5) has the value -2. MODULO(-8, -5) has the value -3.
