Parameters: The function accepts a single parameter

Return Value: It returns rat truncated (toward zero) to a precision of ndigits decimal digits

Example 1:

#Ruby program for truncate() method

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

#Prints the rational number
           puts rat1.truncate()

Output:

-1

Example 2:

#Ruby program for truncate() method

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

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