Ruby | BigDecimal PI() function
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
