What is a max function in Haskell?

Overview

The max function is used to get the maximum of two arguments. We can get the maximum of two integers, two floats, or two characters.

Syntax

max first_argument second_argument

Parameters and return value

This function takes two parameter values to compare and returns the greater value.

Let's have a look at the example below.

Example

main::IO()
main = do
  -- get max of two integers
  print(max 5 10)
  
  -- get max of two floats
  print(max 154.0 34.0)
  -- get max of two characters
  print(max 'a' 'A')

Explanation

In the above code:

  • Line 5: We use the max function to get the max of two integer values.
  • Line 8: We use the max function to get the max of two float values.
  • Line 11: We use the max function to get the max of two characters. We also use the ASCII value to compare the characters.
