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
