Ruby | BigDecimal exp() function

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

# 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

# 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
