Implementation Reference
- cruncher.js:1711-1711 (handler)The 'modulo' tool handler in the toolHandlers object. Delegates to safeMath.modulo(a, b).
modulo: ({ a, b }) => safeMath.modulo(a, b), - cruncher.js:1277-1288 (helper)The safeMath.modulo helper function implementing the modulo logic with safe floating-point arithmetic via integer-scaling.
modulo: (a, b) => { if (b === 0) throw new Error("Modulo by zero is not allowed."); const d1 = countDecimals(a); const d2 = countDecimals(b); const maxDecimals = Math.max(d1, d2); const multiplier = Math.pow(10, maxDecimals); return ( (Math.round(a * multiplier) % Math.round(b * multiplier)) / multiplier ); }, }; - cruncher.js:857-874 (schema)The 'modulo' tool definition in the master tools list, including inputSchema (a: number, b: number), description, and annotations.
