Boosted Calculator

A powerful terminal-based calculator inspired by Numi, built with TypeScript and Ink (React for CLI). Features arbitrary precision arithmetic, advanced math operations, unit conversions, dimensional analysis, live currency conversion, and more.

npm install -g boosted-calc
# or
yarn global add boosted-calc
# or
bun add -g boosted-calc

# Clone the repository
git clone https://github.com/pyboosted/calc
cd calc

# Install dependencies
bun install

# Install globally
npm link

# Run the calculator (interactive mode)
calc

# Open or create a calculation file
calc budget.calc

# Evaluate expression directly
calc -e "2 + 2"
calc -e "100 USD in EUR"
calc -e "sqrt(16) * 2"

# Update currency exchange rates
calc --update

# Simple math
2 + 2                    # 4
10 * (5 + 3)            # 80
sqrt(144)               # 12

# Unit conversions
100 cm in meters        # 1 m
32 °F in °C            # 0 °C
60 km/h to m/s         # 16.667 m/s

# Compound unit input
1h 30min                # 1.5 hours
2kg300g                 # 2.3 kg
100m / 1min30s          # 66.67 m/min

# Variables and functions
radius = 5
area = pi * radius^2    # 78.54
double(x) = x * 2
double(10)              # 20

# Pipe operator
[1, 2, 3, 4, 5] | sum   # 15
"  hello  " | trim | len # 5

# Date calculations
