Number Converter

The plugin to convert numbers from one system to another in any JetBrains IDE. For floating point numbers, the fractional part will be discarded.

Features:

• big integers
• engineering types
• negative conversion (bit shifting)
• multi carets
• shortcuts
• date string to number system conversion (select a date string and convert to DEC/HEX/OCT/BIN/FORMAT)
• configurable seconds/milliseconds timestamp output
• number formatting with grouping, currency symbols, and decimal places
• settings – date format, surrounding, etc.

Current supported systems:

• DEC - Decimal
• HEX - Hexadecimal
• OCT - Octal
• BIN - Binary
• DATE - Date/Time
• FORMAT - Number formatting (grouping, currency)

Usage

1. Select a number or date string in the editor
2. Right-click and choose Convert To... from the context menu
3. Pick the target system (DEC, HEX, OCT, BIN, DATE, FORMAT)

The plugin auto-detects the input format:

• 0x prefix → HEX
• 0b prefix → BIN
• 0 prefix → OCT
• Date strings (matching your configured format) → parsed as date
• Everything else → DEC

Multiple carets are supported — each selection is converted independently.

Shortcuts

Shortcut	Target
Ctrl+Alt+N, D	DEC
Ctrl+Alt+N, H	HEX
Ctrl+Alt+N, O	OCT
Ctrl+Alt+N, B	BIN
Ctrl+Alt+N, T	DATE
Ctrl+Alt+N, F	FORMAT

Settings

Open Settings → Tools → Number Converter to configure the plugin.

Surrounding

• Wrap converted output in configurable left/right strings (e.g. [ and ])

Date format

• Format pattern — SimpleDateFormat pattern used for date display and parsing (default: yyyy-MM-dd HH:mm:ss). Patterns like yyyy-MM-dd HH:mm:ss.SSS are supported for millisecond precision.
• UTC — use UTC timezone instead of local
• Milliseconds — when enabled, timestamps are interpreted and produced as milliseconds instead of seconds. Affects all conversions: number → date and date → number/format.

Formatting

• Upper/Lower Case — controls letter case for HEX output (e.g. 0xFF vs 0xff)

Number format (for FORMAT conversion)

• Delimiter — grouping character (default: ,)
• Group size — digits per group (default: 3)
• Decimals — enable fixed decimal places
• Currency — symbol to prepend or append. To add a custom symbol, type it in the currency dropdown and right-click → Add. To remove a custom symbol, select it and right-click → Remove.
