What is the integer.size method in Ruby?

Overview

The size property of an integer is used to get the number of bytes in the machine representation of int (machine-dependent).

Syntax

integer.size

Return value

The value returned is an integer, which represents the number of bytes in the machine representation of an integer.

Code example

# create integer values
int1 = 10
int2 = 256**20 + 1
int3 = 256**10 - 1
int4 = 300 **4 - 3
# get size
puts "#{int1.size}"
puts "#{int2.size}"
puts "#{int3.size}"
puts "#{int4.size}"

Code explanation

  • Lines 2–5: We create some integer values.
  • Lines 8–11: We use the size property to get the number of bytes of the integers. And then, we print the results to the console.
