Ruby | Rational floor() function
The floor() is an inbuilt function in Ruby returns the largest number less than or equal to rat with 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.floor(ndigits)
Parameters: The function accepts a single parameter
Return Value: It returns the largest number less than or equal to rat with a precision of ndigits decimal digits
Example 1:
# Ruby program for floor() method # Initialize rational numberrat1 = Rational(-4, 3) # Prints the rational numberputs rat1.floor() |
Output:
-2
Example 2:
# Ruby program for floor() method # Initialize rational numberrat1 = Rational('123.456') # Prints the rational numberputs rat1.floor(1)puts rat1.floor(-1) |
Output:
617/5 120
