Given two integers representing the numerator and denominator of a fraction, return the fraction in string format.

If the fractional part is repeating, enclose the repeating part in parentheses.

Example 1:


Input: numerator = 1, denominator = 2
Output: "0.5"


Example 2:


Input: numerator = 2, denominator = 1
Output: "2"

Example 3:


Input: numerator = 2, denominator = 3
Output: "0.(6)"
