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
