Ruby | BigDecimal sqrt() function

BigDecimal#sqrt() : sqrt() is a BigDecimal class method which returns the square root of the value.

Syntax: BigDecimal.sqrt()

Parameter: BigDecimal values

Return: the square root of the value.

Example #1 :

# Ruby code for BigDecimal.sqrt() method

# loading library
require 'bigdecimal'

# declaring bigdecimal
a = BigDecimal("10")

# declaring bigdecimal
b = BigDecimal("1000") *2

# declaring bigdecimal
c = BigDecimal("11.43")

# sqrt() method
puts "BigDecimal a sqrt method : #{Math.sqrt(a)}\n\n"

puts "BigDecimal b sqrt method : #{Math.sqrt(b)}\n\n"

puts "BigDecimal a sqrt method : #{Math.sqrt(c)}\n\n"

Output :

BigDecimal a sqrt method : 3.1622776601683795

BigDecimal b sqrt method : 44.721359549995796

BigDecimal a sqrt method : 3.380828300875393

Example #2 :

# Ruby code for BigDecimal.sqrt() method

# loading library
require 'bigdecimal'

# declaring bigdecimal
a = BigDecimal('12')*12

# declaring bigdecimal
b = BigDecimal('10')+(22 ** 7.1) ** 10

# declaring bigdecimal
c = -BigDecimal('-3')

# sqrt() method
puts "BigDecimal a sqrt method : #{Math.sqrt(a)}\n\n"

puts "BigDecimal b sqrt method : #{Math.sqrt(b)}\n\n"

puts "BigDecimal a sqrt method : #{Math.sqrt(c)}\n\n"

Output :

BigDecimal a sqrt method : 12.0

BigDecimal b sqrt method : 4.5290297054731975e+47

BigDecimal a sqrt method : 1.7320508075688772
