| Description: | Returns the maximum value of the arguments. | ||
| Class: | Elemental function; Generic | ||
| Arguments: | A1, A2, and A3 (opt) must all have the same type (integer or real) and kind parameters. | ||
| Results: | For MAX0, AMAX1, DMAX1, QMAX1, IMAX0, JMAX0, and KMAX0, the result type is the same as the arguments. For MAX1, IMAX1, JMAX1, and KMAX1, the result type is integer. For AMAX0, AIMAX0, AJMAX0, and AKMAX0, the result is of type real. The value of the result is that of the largest argument. | ||
| Specific Name1 | Argument Type | Result Type |

| INTEGER(1) | INTEGER(1) | |
| INTEGER(1) | REAL(4) | |
| IMAX0 | INTEGER(2) | INTEGER(2) |
| AIMAX0 | INTEGER(2) | REAL(4) |
| MAX0 2 | INTEGER(4) | INTEGER(4) |
| AMAX0 3,4 | INTEGER(4) | REAL(4) |
| KMAX0 | INTEGER(8) | INTEGER(8) |
| AKMAX0 | INTEGER(8) | REAL(4) |
| IMAX1 | REAL(4) | INTEGER(2) |
| MAX1 4,5,6 | REAL(4) | INTEGER(4) |
| KMAX1 | REAL(4) | INTEGER(8) |

1 These specific functions cannot be passed as actual
arguments.
2 Or JMAX0. 3 Or AJMAX0. AMAX0 is the same as REAL (MAX). 4 In Fortran 90, AMAX0 and MAX1 are specific functions with no generic name. For compatibility with older versions of Fortran, these functions can also be specified as generic functions. 5 Or JMAX1. MAX1 is the same as INT (MAX). 6 The setting of compiler options specifying integer size can affect MAX1. 7 The setting of compiler options specifying real size can affect AMAX1. | ||
Examples
MAX (2.0, -8.0, 6.0) has the value 6.0.
MAX (14, 32, -50) has the value 32.
