  • Last Updated : 06 Dec, 2019

BigDecimal#PI() : PI() is a BigDecimal class method which returns the value of pi to the specified number of digits of precision, numeric.

Syntax: BigDecimal.PI()

Parameter: BigDecimal values

Return: the value of pi to the specified number of digits of precision, numeric.

Example #1 :






# Ruby code for BigDecimal.PI() method
  
# loading library
require 'bigdecimal'
require 'bigdecimal/util'
  
require "bigdecimal/math"
  
include BigMath
  
# declaring bigdecimal
a = BigMath.PI(10).to_s
  
# declaring bigdecimal
b = BigMath.PI(102).to_s
  
# declaring bigdecimal
c = BigMath.PI(2).to_s
  
# PI() method
puts "BigDecimal a PI method : #{a}\n\n"
  
puts "BigDecimal b PI method : #{b}\n\n"
  
puts "BigDecimal c PI method : #{c}\n\n"

Output :

BigDecimal a PI method : 0.3141592653589793238462643388813853786957412E1

BigDecimal b PI method : 0.3141592653589793238462643383279502884197169399375105820974944592307816406286208998628034825342117067982148086513282306913173228884424E1

BigDecimal c PI method : 0.31415926535897932388671233672993238433E1

Example #2 :




# Ruby code for BigDecimal.PI() method
  
# loading library
require 'bigdecimal'
require 'bigdecimal/util'
  
require "bigdecimal/math"
  
include BigMath
  
# declaring bigdecimal
a = BigMath.PI(78).to_s
  
# declaring bigdecimal
b = BigMath.PI(12).to_s
  
# declaring bigdecimal
c = BigMath.PI(1).to_s
  
# PI() method
puts "BigDecimal a PI method : #{a}\n\n"
  
puts "BigDecimal b PI method : #{b}\n\n"
  
puts "BigDecimal c PI method : #{c}\n\n"

Output :

BigDecimal a PI method : 0.31415926535897932384626433832795028841971693993751058209749445923078164062862089986280348253422571844827786301E1

BigDecimal b PI method : 0.314159265358979323846264338336544487694763327962E1

BigDecimal c PI method : 0.31415926535897932364198143965603E1
