Ruby Integer ceil function with example Last Updated : 07 Jan, 2020 Comments Improve Suggest changes Like Article Like Report The ceil function in Ruby returns the smallest number greater than or equal to int with a precision of ndigits decimal digits. The default is considered to be 0. When the precision given is negative, the returned value is an integer with at least ndigits.abs trailing zeros. It returns self when ndigits positive. Syntax: (number).ceil(ndigits) Parameter: The function takes the integer whose ceil value is to be returned and a single parameter ndigits which specifies the precision to be returned. Return Value: The function returns the smallest integer number greater than or equal to it. Example #1: Ruby # Ruby program of ceil function # Initializing the numbers num1 = 10 num2 = 17 num3 = 17.5 num4 = 21.5 # Prints the ceil value puts num1.ceil puts num2.ceil(1) puts num3.ceil(0) puts num4.ceil(2) Output: 10 17.0 18 21.5 Example #2: Ruby # Ruby program of ceil function # Initializing the numbers num1 = 13 num2 = -90 num3 = 90 num4 = 81.7 # Prints the ceil value puts num1.ceil puts num2.ceil(2) puts num3.ceil(-1) puts num4.ceil(0) Output: 13 -90.0 90 82 Comment More infoAdvertise with us Next Article Ruby Integer ceil function with example G gopaldave Follow Improve Article Tags : Ruby Ruby-Methods Ruby Integer-class Similar Reads Ruby Integer div() function with example The div() function in Ruby returns the integer division of two numbers.
