Introduction

Yukihiro Matsumoto desired a scripting language that was more powerful than Perl and more object-oriented than Python, so he created Ruby.

Ruby is an open-source, interpreted, high-level, dynamic, general-purpose programming language focusing on productivity and simplicity.

As you'd expect from a contemporary language, Ruby has many operators. In this blog, we will discuss Ruby's double splat operator(**).

Let's get started with the ** operator in Ruby.

Double Splat Operator (**)

A symbol denoting an operation performed with one or more operands is called an operator. Any programming language's base is made up of operators. We may use operators to execute a variety of actions on operands.

In Ruby, several distinct types of operators; we'll discuss the Exponentiation operator.

** operator is used to return the exponential power of the operators. For example, a**b.

It performs Exponentiation, which means it raises the first argument to the power of the second.

It's worth noting that a fractional number can be used as the second argument to compute the roots of a number. For example, the cube root of a is a**(1.0/3.0). Similarly, a**-b is the same as 1/(a**b).

def function_name(**double_splat)

Power of number using ** operator

The task is to develop a program that prints the power of a number using a double splat operator in Ruby programming language.

If we wish to manually compute a number's power, we must multiply the base by the exponent times. For example, if the base is 5 and the exponent is 3, the power will be calculated as

The answer is 125 if power = 5*5*5.

The following methods were used:

gets: This function takes user input in the form of a string.

puts: This command initiates a dialogue with the user by displaying a message on the console.

to_i: To convert any type to an integer type.

Program

=begin
power of a number using ** operator
=end

base=gets.chomp.to_i

exponent=gets.chomp.to_i

power=base**exponent
puts "The power of #{base} is #{power}"

Input

2
3

Output

The power of 2 is 8

Frequently Asked Questions

Is there operator overloading in Ruby?

Ruby has operator overloading, which allows you to specify how an operator will be used in a program.

In Ruby, what are class libraries?

Ruby class libraries cover many topics, including thread programming, data types, and other disciplines.

Name some of the Ruby operators.

Some operators used in Ruby are a unary, arithmetic, bitwise, logical operator, and ternary operator.

What exactly are Ruby blocks?

Closures are what other programming languages call Ruby code blocks. It comprises a collection of codes that are always contained in braces or written between do...end.

Conclusion

In this article, we learned about Ruby's ** operators and how to use a double splat operator to calculate the power of a number. This isn't enough, though, because there's always more to discover and understand about Ruby in depth.
