DIM — Positive difference#
-
DIM(X, Y)#
DIM(X,Y)
returns the differenceX-Y
if the result is positive; otherwise returns zero.- Parameters
X – The type shall be
INTEGER
orREAL
Y – The type shall be the same type and kind as
X
. (As a GNU extension, arguments of different kinds are permitted.)
- Returns
The return value is of type
INTEGER
orREAL
. (As a GNU extension, kind is the largest kind of the actual arguments.)
- Standard:
Fortran 77 and later
- Class:
Elemental function
- Syntax:
RESULT = DIM(X, Y)
- Example:
program test_dim integer :: i real(8) :: x i = dim(4, 15) x = dim(4.345_8, 2.111_8) print *, i print *, x end program test_dim
