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
