Calculator Skill
Perform mathematical calculations and unit conversions.
Usage
Calculate Expressions
python3 scripts/calculator.py calc "<expression>"
Supported operations:
- Basic arithmetic:
+,-,*,/,%,^(or**) - Parentheses for grouping:
(2 + 3) * 4 - Percentage:
50%→0.5,100 + 10%→110
Math functions:
- Trigonometric:
sin(),cos(),tan(),asin(),acos(),atan() - Hyperbolic:
sinh(),cosh(),tanh() - Logarithms:
log()(natural),log10(),log2(),ln() - Powers/roots:
sqrt(),pow(),exp() - Rounding:
round(),floor(),ceil() - Other:
abs(),max(),min(),factorial(),gcd() - Constants:
pi,e - Angle conversion:
degrees(),radians()
Examples:
python3 scripts/calculator.py calc "2 + 2"
python3 scripts/calculator.py calc "sin(pi/2)"
python3 scripts/calculator.py calc "sqrt(16) + log(10)"
python3 scripts/calculator.py calc "(100 - 20) * 1.5"
python3 scripts/calculator.py calc "2^10"
python3 scripts/calculator.py calc "50% of 200"
Unit Conversions
python3 scripts/calculator.py convert <value> <from_unit> <to_unit>
Supported categories:
| Category | Units |
|---|---|
| Length | m, km, cm, mm, mi, yd, ft, in, nm |
| Mass | g, kg, mg, lb, oz, t/ton |
| Volume | l, ml, gal, qt, pt, cup, fl oz, tbsp, tsp |
| Area | m², km², cm², ha, acre, ft², in² |
| Time | s, min, h, d, wk, mo, y |
| Temperature | °C, °F, K |
Examples:
python3 scripts/calculator.py convert 100 km miles
python3 scripts/calculator.py convert 70 f c
python3 scripts/calculator.py convert 2.5 kg lb
python3 scripts/calculator.py convert 500 ml cups
Output Format
All commands output JSON:
{"result": 42}
{"result": 3.14159, "category": "length"}
{"error": "Division by zero"}
Error Handling
Common errors and their meanings:
Division by zero- Attempted to divide by zeroInvalid expression syntax- Malformed expressionUnknown function or variable- Used unsupported function/variableUnsupported unit conversion- Units not in same category or not recognized
