The pred function in Ruby returns the immediate predecessor of the number, i.e., it returns number - 1. If a float value is used, it throws an error message.

Syntax: number.pred Parameter: The function takes the integer whose predecessor is to be returned. Return Value: The function returns the immediate predecessor of the number, i.e., it returns number - 1

Example 1:

Ruby

# Ruby program for pred function
 
# Initializing the numbers 
num1 = 100
num2 = 17
num3 = -90
num4 = -29
   
# Printing the pred value
puts num1.pred
puts num2.pred
puts num3.pred 
puts num4.pred

Output:

Example 2:

Ruby

# Ruby program for pred function
 
# Initializing the numbers 
num1 = 19
num2 = -17
num3 = -18
num4 = 16
     
# Printing the pred value
puts num1.pred
puts num2.pred
puts num3.pred 
puts num4.pred
