Infinite Value (BigDecimal)

[Website] [Online Demo] [User Manual] [Public API]

InfVal is an arbitrary-precision number type for Unity.

It stores any integer or decimal value and behaves like a primitive: full arithmetic, comparison, and bitwise operators, implicit casts from all numeric types, and direct inspector support.

Designed for real-time use and fully serializable.

Perfect for incremental games, RPGs, or any system where standard numeric types overflow or lose precision.

Features

• Arbitrary precision: integer or decimal with any digit count; values up to ~±10^4,294,967,295 with precision down to 10^−2,147,483,648
• Primitive-like API: arithmetic (+, -, *, /, %), bitwise, and comparison operators; implicit casts from all numeric primitives
• Formatter system: 5 built-in formatters (Manual, Scientific, Alphabetic, Culture-aware with native East Asian units, Conway-Guy number names) and a custom formatter interface; assign formatters project-wide or per component
• Inspector drawer: edit values directly, access raw digits and exponent, call transform methods with one click, and view all read-only properties, all sections configurable
• Input field component: InfValInputField turns any InputField or TMP_InputField into an InfVal field with validation modes, sign constraints, and per-component formatter override
• Math & interpolation: 30+ methods in MathInfVal (Abs, Pow, Sqrt, Log, Clamp, RandomRange, …) and 10+ interpolation modes in InterpolateInfVal including ease in/out and angle variants
• Performant: explicit precision control, in-parameter passing, and ToString() caching keep real-time use efficient
• Full sources: all scripts included with comments and summaries
