Calculator

ZetoPad includes a powerful calculator that evaluates mathematical expressions inline.

Opening the Calculator Panel

1. Press Cmd+Shift+C or
2. Click the calculator icon in the toolbar
3. Or use Command Palette: “Toggle Calculator”

Inline Evaluation

The calculator evaluates expressions as you type in your snippets:

2 + 2 = 4
100 * 0.15 = 15
sqrt(144) = 12

Practical Examples

Percentage Calculations

500 * 0.2 = 100      # 20% of 500
250 / 0.8 = 312.5    # Number that 250 is 80% of

Unit Conversions

# Fahrenheit to Celsius
(98.6 - 32) * 5/9 = 37

# Miles to Kilometers
26.2 * 1.60934 = 42.16

Programming Math

# Binary to decimal
2^7 + 2^5 + 2^0 = 161

# Array index calculation
(15 * 1024) + 256 = 15616

Tips

• Results update in real-time as you type
• Use parentheses for complex expressions
• Calculator respects your snippet content - results appear as comments
