Description

Calculate the remainder of dividing two double-precision floating-point numbers, $a$ and $b$, where both $a$ and $b$ are double-precision floating-point numbers. The remainder $(r)$ is defined as: $a = k \times b + r$, where $k$ is an integer, and $0 \leq r < b$.

Input Format

The input consists of a single line containing two double-precision floating-point numbers, $a$ and $b$.

Output Format

The output is a single line, the remainder of $a \div b$.
