SKILL.md

Calculator

Evaluate arithmetic expressions with arbitrary-precision decimal math using big.js.

When to Use

User asks to calculate or evaluate a math expression
Precise decimal arithmetic is needed (avoids floating-point errors like 0.1 + 0.2 = 0.30000000000000004)
Expressions involve parentheses, operator precedence, or exponents

Supported Operations

Operator	Description	Precedence
`+`	Addition	1
`-`	Subtraction	1
`*`	Multiplication	2
`/`	Division	2
`^`	Exponent (right-associative)	3
`()`	Parentheses	Highest

Usage

bash

cd scripts
npm ci || npm install
npm run build
npm run calculate "<expression>"

Examples

Input	Output
`"3 + 2"`	`5`
`"10 / 4"`	`2.5`
`"2 ^ 10"`	`1024`
`"(2 + 3) * 4"`	`20`
`"1 + 4.5 * (3-6) / 5"`	`-1.7`
`"-5 + 3"`	`-2`
`"2 ^ 3 ^ 2"`	`512` (right-associative: 2^9)

Edge Cases

Empty expression: Throws "Empty expression" error
Mismatched parentheses: Throws "Mismatched parentheses" error
Division by zero: big.js throws an error
Exponent must be integer: big.js .pow() requires integer exponents

Limitations

No trigonometric functions (sin, cos, tan)
No variables or symbolic math
Exponents must be integers
No factorial, modulo, or bitwise operators
