Ruby - arithmetic operators example



The example below shows the usage of arithmetic operators - addition(+), subtraction(-), multiply(*), division(/), modulo(%), and exponent(**) operators.

a = 9.0
b = 2.0

puts "a = #{a}, b = #{b} \n\n"

#Add a and b
result_add = a + b
puts "a + b = #{result_add}"

#Subtract b from a
result_sub = a - b
puts "a - b = #{result_sub}"

#Multiply a and b
result_mul = a * b
puts "a * b = #{result_mul}"

#Divide a by b
result_div = a / b
puts "a / b = #{result_div}"

#return division remainder
result_modulo = a % b
puts "a % b = #{result_modulo}"

#a raised to the power of b
result_pow = a ** b
puts "a ** b = #{result_pow}"

The output of the above code will be:

a = 9.0, b = 2.0 

a + b = 11.0
a - b = 7.0
a * b = 18.0
a / b = 4.5
a % b = 1.0
a ** b = 81.0
