Ruby | Rational rationalize() function

The rationalize() is an inbuilt function in Ruby returns a simpler approximation of the value if the optional argument eps is given (rat-|eps| <= result <= rat+|eps|) otherwise returns its self.

Syntax: rat.rationalize(eps)

Parameters: The function accepts a single optional parameter

Return Value: It returns a simpler approximation of the value if the optional argument eps is given (rat-|eps| <= result <= rat+|eps|) otherwise returns its self

Example 1:

# Ruby program for rationalize() method

# Initialize rational number
rat1 = Rational(123, 456)

# Prints the rational number
puts rat1.rationalize

Output:

41/152

Example 2:

# Ruby program for rationalize() method

# Initialize rational number
rat1 = Rational(123, 456)

# Prints the rational number
puts rat1.rationalize(Rational('.001'))

Output:

7/26
