Calculator

Perform calculations using shell tools.

Arithmetic

• Basic math: echo "scale=4; 355/113" | bc -l
• Percentages: echo "scale=2; 847 * 0.15" | bc -l
• Powers: echo "2^32" | bc
• Square root: echo "scale=4; sqrt(2)" | bc -l

Python (if available)

For complex math: python3 -c "import math; print(math.log2(1024))"

Unit conversions

• Bytes to human: numfmt --to=iec 1073741824 (gives 1.0G)
• Human to bytes: numfmt --from=iec 4G (gives 4294967296)
• Temperature: python3 -c "c=37; print(f'{c}C = {c*9/5+32}F')"

Date math

• Days between dates: echo $(( ($(date -d 2025-12-31 +%s) - $(date +%s)) / 86400 )) days
• Date in N days: date -d "+30 days" +%Y-%m-%d
• Timestamp to date: date -d @1700000000
