subtract
Calculate the difference between two numbers with 64-bit floating point precision. Supports integers, decimals, and fractions to perform subtraction operations.
Instructions
Subtracts two numbers with 64 bit floating point precision and returns a 64 bit float. For example, subtracting 5 from 10 would return 5.0. You can also use fractions if you want to, like 1/2 for number_1 and 1/3 for number_2.

Implementation Reference
- src/math_server.py:58-69 (handler)The core handler function for the 'subtract' tool. It is registered using the @math_mcp.tool decorator on the FastMCP server instance. The function signature provides the input schema (two numbers: int | float), docstring describes usage and output (float), and the body computes the subtraction with 64-bit precision using NumPy, including logging.
