Return value:
The return value corresponds to the maximum value among the arguments, and has the same type and kind as the first argument.
Specific names:
| Name | Argument | Return type | Standard |
|---|---|---|---|
| MAX0(A1) | INTEGER(4) A1 | INTEGER(4) | Fortran 77 and later |
| AMAX0(A1) | INTEGER(4) A1 | REAL(MAX(X)) | Fortran 77 and later |
| MAX1(A1) | REAL A1 | INT(MAX(X)) | Fortran 77 and later |
| AMAX1(A1) | REAL(4) A1 | REAL(4) | Fortran 77 and later |
