Ruby | Rational truncate() function

Last Updated : 19 Mar, 2024

The truncate() is an inbuilt function in Ruby returns rat truncated (toward zero) to a precision of ndigits decimal digits. ndigits by default is 0. It returns a rational when ndigits is positive, otherwise returns an integer.

Syntax: rat.truncate(ndigits) Parameters: The function accepts a single parameter Return Value: It returns rat truncated (toward zero) to a precision of ndigits decimal digits

Example 1:

CPP

#Ruby program for truncate() method

#Initialize rational number
rat1 = Rational(-4, 3)

#Prints the rational number
           puts rat1.truncate()

Output:

-1

Example 2:

CPP

#Ruby program for truncate() method

#Initialize rational number
rat1 = Rational('123.456')

#Prints the rational number
           puts rat1.truncate(1)
               puts rat1.truncate(-1)

Output:

617/5
120
