Does this tool use floating-point numbers?

No. The engine uses integer arithmetic for numerators and denominators, ensuring absolute precision without any rounding errors.

How can I convert a mixed number to an improper fraction?

You can use the `parse_rational` tool or perform arithmetic operations that automatically return results in simplified improper fraction form.

What is the output format for repeating decimals?

The `expand_to_decimal` tool uses a specialized overline notation to clearly mark the repeating part of the decimal expansion.

The Fraction Exact Calculator is a specialized engine for high-precision rational number arithmetic. It eliminates the inaccuracies of floating-point math by performing all operations using integer-based numerator and denominator logic. This MCP server allows AI agents to perform calculate_operation for addition, subtraction, multiplication, and division; use parse_rational to decompose fractions into components; apply analyze_continued_function to find coefficients and convergents; and utilize expand_to_decimal to identify terminating or repeating decimal patterns with exact overline notation.
