Ruby Float ceil() method with example

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

Syntax: float.ceil()

Parameter: float value which is to get its ceil 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 ceil() method

# declaring float values
a = -56.23333333

# declaring float values
b = 56.784

# declaring float values
c = 222.8868686

# 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 : -56

ceil value of b : 57

ceil value of c : 223

Example #2 :

# Ruby code for ceil() method

# declaring float values
a = -0.78779393

# declaring float values
b = -50006.784 + 34

# declaring float values
c = 289 + 22.8868686

# 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 : 0

ceil value of b : -49972

ceil value of c : 312
