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:
#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)
|
Output:
617/5 120
