Given two floating point numbers a and b, find a%b.

Example 1:

Input:
a = 36.5, b = 5.0
Output:
1.5
Explanation:
36.5 % 5.0 = 1.5

Example 2:

Input:
a = 9.7, b = 2.3
Output:
0.5
Explanation:
9.7 % 2.3 = 0.5

Your Task:
You don't need to read input or print anything. Your task is to complete the function floatMod() which takes 2 doubles a, and b as input and returns a%b.

Expected Time Complexity: O(1)
Expected Auxiliary Space: O(1)

Constraints:
1 <= a,b<= 10³
