# min()

(Macro) Calculates the minimum of two numbers.

## Syntax

    min(x,y)

## Parameters

x: the first number; may be any number or numeric expression.

y: the second number; may be any number or numeric expression.

## Returns

The smaller of the two numbers.

## Example

    sensVal = min(sensVal, 100); // assigns sensVal to the smaller of sensVal or 100
                                 // ensuring that it never gets above 100.

Note

Perhaps counter-intuitively, max() is often used to constrain the lower end of a variable’s range, while min() is used to constrain the upper end of the range.

## Warning

Because of the way `min()` is implemented, avoid using other functions inside the parentheses. It may lead to incorrect results:

    min(a++, 100);   // avoid this - yields incorrect results

    a++;            // use this instead -
    min(a, 100);    // keep other operations outside min()

## Arduino Compatibility

The Maple version of `min()` is compatible with Arduino.
