Ruby Float floor() method with example

floor() is a float class method which return the floor value of the passed float value.

Syntax: float.floor()

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

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

Example #1:

# Ruby code for floor() method

a = -56.23333333

b = 56.784

c = 222.8868686

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

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

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

Output :

floor value of a : -57

floor value of b : 56

floor value of c : 222

Example #2:

# Ruby code for floor() method

a = -0.78779393

b = -50006.784 + 34

c = 289 + 22.8868686

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

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

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

Output :

floor value of a : -1

floor value of b : -49973

floor value of c : 311
