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:

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 zero
• Invalid expression syntax - Malformed expression
• Unknown function or variable - Used unsupported function/variable
• Unsupported unit conversion - Units not in same category or not recognized
