BigDecimal#exp() : exp() is a BigDecimal class method which returns the value of e (the base of natural logarithms) raised to the power of decimal, to the specified number of digits of precision.
Syntax: BigDecimal.exp() Parameter: BigDecimal values Return: the value of e (the base of natural logarithms) raised to the power of decimal
Example #1 :
# Ruby code for BigDecimal.exp() method
# loading library
require 'bigdecimal'
# declaring bigdecimal
a = BigDecimal("10")
# declaring bigdecimal
b = BigDecimal("1000") *2
# declaring bigdecimal
c = BigDecimal("11.43")
# exp() method
puts "BigDecimal a exp method : #{Math.exp(a)}\n\n"
puts "BigDecimal b exp method : #{Math.exp(b)}\n\n"
puts "BigDecimal c exp method : #{Math.exp(c)}\n\n"
Output :
BigDecimal a exp method : 22026.465794806718 BigDecimal b exp method : Infinity BigDecimal c exp method : 92041.97481768382
Example #2 :
# Ruby code for BigDecimal.exp() 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')
# exp() method
puts "BigDecimal a exp method : #{Math.exp(a)}\n\n"
puts "BigDecimal b exp method : #{Math.exp(b)}\n\n"
puts "BigDecimal c exp method : #{Math.exp(c)}\n\n"
Output :
BigDecimal a exp method : 3.454660656717546e+62 BigDecimal b exp method : Infinity BigDecimal c exp method : 20.085536923187668
