I previously covered some of the base math functions available. This time I’ll cover the math functions that are related to working with arrays of numbers. This includes the max, min, rand, and range functions.
These two functions work the exact same way. The max function returns the largest number in an array of numbers, and the min function returns the smallest number in an array of numbers. The format is as follows:
max(number1, number2, number3, ....) max([number1, number2, number3, ....]) min(number1, number2, number3, ....) min([number1, number2, number3, ....])
The numbers can be of any type (integer, float or a mixture) and the  brackets are optional if you’re passing in a literal array. You can also pass in a single array variable. The result will be a single number which is either the largest or smallest number respectively.
max(2.1, 4, 6.4, 8) //returns 8 min(2.1, 4, 6.4, 8) //returns 2.1
The range function will allow you to generate an array of integers. The format is as follows:
The startingNumber is the number at which you want to start the array. And the numberCount is the number of items to add to the array. Each number added will be one higher than the last. Only integer numbers are supported, and not float numbers.
range(5,5) //will return [5,6,7,8,9] range(11,7) //will return [11,12,13,14,15,16,17]
The rand function will return a random integer number between two provided numbers, inclusive of the starting number and exclusive of the ending number. The format is as follows:
Only integer numbers are supported and not float numbers.
rand(1,5) //will return 1, 2, 3, or 4 rand(21,28) //will return 21, 22, 23, 24, 25, 26, or 27
