Arduino Programming Language: Min

Name

min()

Description

Calculates the minimum of two numbers.

Syntax

min(x, y)

Parameters

  • x: the first number, any data type
  • y: the second number, any data type

Returns

 The smaller of the two numbers

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 the min() function is implemented, avoid using other functions inside the brackets, it may lead to incorrect results:

min(a++, 100); // avoid this - yields incorrect results
min(a, 100);
a++; // use this instead - keep other math outside the function

Examples

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