DIM
Elemental Intrinsic Function (Generic): Returns the difference between two numbers (if the difference is positive).
result = DIM (x, y)
x |
(Input) Must be of type integer or real. |
y |
(Input) Must have the same type and kind parameters as x. |
Results
The result type and kind are the same as x. The value of the result is x- y if x is greater than y; otherwise, the value of the result is zero.
The setting of compiler options specifying integer size can affect this function.

1Or HDIM. 2Or JIDIM. For compatibility, IDIM can also be specified as a generic function for integer types. |
Example
DIM (6, 2) has the value 4.
DIM (-4.0, 3.0) has the value 0.0.
The following shows another example:
INTEGER i
REAL r
REAL(8) d
i = IDIM(10, 5) ! returns 5
r = DIM (-5.1, 3.7) ! returns 0.0
d = DDIM (10.0D0, -5.0D0) ! returns 15.0D0
