Ruby Integer succ() function with example
  • Last Updated : 03 Dec, 2020

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

Syntax: number.succ 

Parameter: The function takes the integer whose next is to be returned. 

Return Value: The function returns the immediate successor of the number, i.e., it returns number + 1

Example 1:

code

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