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"
ceil value of a : -56 ceil value of b : 57 ceil value of c : 223Example #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"
ceil value of a : 0 ceil value of b : -49972 ceil value of c : 312
