Calculate the remainder of two double-precision floating point numbers a and B. both a and B are positive numbers. Here, the remainder (r) is defined as: a = k * B + r, where k is an integer and 0 <= r <B. Enter the numbers a and B separated by two spaces in a row. The remainder of output a divided by B (two decimal places are reserved for the answer ). Sample Input
