Submitted by user pgelvin; MIT; 2024-01-20

A lightweight RPN calculator.

Note: This addon utilizes GDExtension. If you have errors after installing, please reload your project so the GDExtension can be correctly loaded.

= Extended Types

RCalc can understand scalar types like integers and real numbers, as well as vectors and square matrices of sizes 2, 3, and 4.
When operating purely in the scalar integer domain, RCalc can promote up to BigInts to avoid floating point imprecision.


= 84 Operators

RCalc has 84 built-in operators with included documentation and examples.
All the expected operators (basic arithmetic, exponents, logarithms) are present, as are:

- Rounding functions (floor/ceil/trunc/round)
- Unit conversions
- Bitwise operations (and/or/not/xor/shift left/shift right)
- Statistics (avg/min/max/sum/std dev/NPV)
- Trigonometry (sin/cos/tan + arc/hyperbolic variants)
- Vector operations (dot/cross/normalize/length/swizzle)
- Matrix operations (identity/inverse/transpose + translation/scale/rotation matrix generators)


= Unit Conversions

RCalc has 74 built-in units, and can convert between units within families, including:

- Angle
- Area
- Colors (3 and 4 components)
- Coordinate systems (2D and 3D)
- Length
- Mass
- Storage (Base 10 [SI, 1000 bytes in a kb] and Base 2 [1024 bytes in a kb])
- Temperature
- Time
- Volume


= Value Representation

RCalc recognizes values represented in binary, octal, decimal, and hexidecimal. You can:

- Enter values in one representation, and convert them to another
- See the result of bitwise operations in binary automatically
- View vec3 and vec4 components (truncated) in hexidecimal when working with colors.
