# max()

(Macro) Calculates the maximum of two numbers.

## Syntax

    max(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 larger of the two parameter values.

## Example

    sensVal = max(senVal, 20); // assigns sensVal to the larger of sensVal or 20
                               // (effectively ensuring that it is at least 20)

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

    max(a--, 0);   // avoid this - yields incorrect results

    a--;           // use this instead -
    max(a, 0);     // keep other operations outside max()

## Arduino Compatibility

The Maple implementation of `max()` is compatible with Arduino.
