Code #1 : Example for *() method
 

Ruby




# Ruby code for BigDecimal.*() method
   
# loading BigDecimal
require 'bigdecimal'
   
# declaring BigDecimal
a = 42.1**13
   
# declaring BigDecimal
b = -BigDecimal("10")
   
# declaring BigDecimal
c = -(22 * 7.1) ** 10
 
# multiplicative value
puts "BigDecimal a * b : #{a*b}\n\n"
 
# multiplicative value
puts "BigDecimal b * c : #{b*c}\n\n"
 
# multiplicative value
puts "BigDecimal a * c : #{c*a}\n\n"

Output : 
 

BigDecimal a * b : -0.1305170490200644E23

BigDecimal b * c : 0.8645901738210328E23

BigDecimal a * c : -1.1284375809886571e+43

Code #2 : Example for *() method 
 

Ruby




# Ruby code for BigDecimal.*() method
   
# loading BigDecimal
require 'bigdecimal'
   
# declaring BigDecimal
a = 12**12 - 27
   
# declaring BigDecimal
b = BigDecimal('10')-(22 * 7.1) ** 10
   
# declaring BigDecimal
c = BigDecimal('-3')
 
# multiplicative value
puts "BigDecimal a * b : #{a*b}\n\n"
 
# multiplicative value
puts "BigDecimal b * c : #{b*c}\n\n"
 
# multiplicative value
puts "BigDecimal a * c : #{c*a}\n\n"

Output : 
 

BigDecimal a * b : -0.7708772836340099569698794810751771E35
