# nmax, nmin - Numerical Extremum Functions

Other versions: 7.31 | 7.40 | 7.54

### Syntax Forms

`... nmax|nmin( val1 = arg1 val2 = arg2 [val3 = arg3] ... [val9 = arg9] ) ...`

### Effect

These functions return the value of the biggest or the smallest of the arguments passed. At least two arguments, `arg1` and `arg2`, and a maximum of nine arguments must be passed, whereby the optional input parameters `val3` to val9 must be filled in ascending order without gaps. The arguments `arg1` to `arg9` are numerical expression positions.

The following applies for the data type of the return value:

• In an arithmetic expression, the arguments of the function contribute to the calculation type of the entire expression and the function is calculated using the calculation type. If an argument itself is an arithmetic expression, its operands contribute to the entire calculation type and the argument is also calculated using this type.

Notes

`result =  nmax|nmin( val1 = arg1 val2 = arg2 )`

the evaluation of the functions is equivalent to:

`IF num1 >= num2 | num1 <= num2.   result = num1. ELSE.   result = num2. ENDIF.`

When using more than two input parameters, an equivalent control structure would be more complex.

Example

For a demonstration of the extremum functions `nmax` and `nmin`, refer to the extremum functions `nmax`, `nmin`.
