DIM — Positive difference#

DIM(X, Y)#

DIM(X,Y) returns the difference X-Y if the result is positive; otherwise returns zero.

Parameters
  • X – The type shall be INTEGER or REAL

  • 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 or REAL. (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
