Lua max()

Lua’s math.max() function is a standard function that is a part of the math library, and it is the best solution for determining the maximum value from a list of numerical inputs, regardless of the number of values in this list. Whether the task is just simple arithmetic or a complex mathematical algorithm, math.max() is a versatile and fundamental helper function for a variety of cases.

Note: math.min() is the opposing function, which will return the minimum value among a set of numerical values.

Syntax

Since max() is a method from Lua’s library math, it is called as math.max().

math.max(value1, value2, value3, .....)

math.max() returns the maximum value among the input numerical values.

Example 1

To find the highest value among three variables:

a = 22
b = 23
c = 24
