Ruby | BigDecimal class floor value

BigDecimal#floor() : floor() is a BigDecimal class method which return the floor value of the passed BigDecimal value.

Syntax: BigDecimal.floor()

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

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

Code #1 : Example for floor() method

# Ruby code for floor() method

# loading BigDecimal
require 'bigdecimal'

# declaring BigDecimal
a = 42.1**13

# declaring BigDecimal
b = -BigDecimal("10")

# declaring BigDecimal
c = -(22 ** 7.1) * 10

# floor value of a
puts "floor value of a : #{a.floor}\n\n"

# floor value of b
puts "floor value of b : #{b.floor}\n\n"

# floor value of c
puts "floor value of c : #{c.floor}\n\n"

Output :

floor value of a : 1305170490200643862528

floor value of b : -10

floor value of c : -33978252068

Code #2 : Example for floor() method

# Ruby code for floor() 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')


# floor value of a
puts "floor value of a : #{a.floor}\n\n"

# floor value of b
puts "floor value of b : #{b.floor}\n\n"

# floor value of c
puts "floor value of c : #{c.floor}\n\n"

Output :

floor value of a : 8916100448229

floor value of b : -205121100730586399999999999999999999999999999999999999999999999999999999999999999999999999999990

floor value of c : -3
