Parameter:
– BigDecimal value which is to get its ceil value
– decimal digits (default = 0)

– smallest number >= to BigDecimal with a ndigits decimal point precision.
– For -ve precision : Integer with at least ndigits.abs trailing zeros.

Code #1 : Example for ceil() method




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

Output :

ceil value of a : 1305170490200643862528

ceil value of b : -10

ceil value of c : -33978252067

Code #2 : Example for ceil() method




# Ruby code for ceil() 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')
  
  
# ceil value of a
puts "ceil value of a : #{a.ceil}\n\n"
  
# ceil value of b
puts "ceil value of b : #{b.ceil}\n\n"
  
# ceil value of c
puts "ceil value of c : #{c.ceil}\n\n"

Output :

ceil value of a : 8916100448229

ceil value of b : -205121100730586399999999999999999999999999999999999999999999999999999999999999999999999999999990

ceil value of c : -3
