On-Screen Numpad

No need to leave the mouse to enter numbers!

An on-screen numpad addon for Blender's numeric property input. Simply press a hotkey while your mouse cursor is over a property field to display a calculator-enabled numeric input dialog.

Features

🖱️ Mouse-Optimized

• Enter numbers without leaving the mouse
• Works with almost all numeric properties in Blender (Transform values, node settings, light/camera settings, etc.)

🧮 Calculator Functions

• Arithmetic, power operations, calculations with parentheses
• Math functions (sin, cos, tan, sqrt, log, abs, etc.)
• Math constants (pi, e, tau)

50*2.54         → 127    (inch to cm conversion)
2*pi*5          → 31.416 (circumference of radius 5)
sqrt(2)         → 1.414  (diagonal ratio)

📐 Automatic Angle Conversion

• When enabled, numeric inputs are automatically treated as degrees and converted to radians
• You can also use explicit conversion functions for precise control

// When Auto Angle Conversion is enabled
360/4           → 1.571  (auto conversion)
degrees(tau/4)  → 1.571  (explicit degree input)

// Manual conversion (when disabled)
radians(360/4)  → 1.571  (explicit radian conversion)
tau/4           → 1.571  (direct radian value)
