🧮 tinymath

[📚 docs ] [🐙 github ]

The fastest Go math library for constrained environments, like microcontrollers or WebAssembly.

• Optimizes for performance and small code size at the cost of precision.
• Uses float32 because most microcontrollers (like ESP32) have much faster computation for float32 than for float64.
• Designed and tested to work with both Go and TinyGo, hence the name.
• Most algorithms are ported from micromath Rust library.
• Zero dependency.

📦 Installation

go get github.com/orsinium-labs/tinymath

🔧 Usage

fmt.Println(tinymath.Sin(tinymath.Pi))

🔬 Size

Here is a comparison of WebAssembly binary size (built with TinyGo) when using tinymath vs stdlib math:

| function | tinymath | stdlib | ratio | | ------------ | --------:| ------:| -----:| | atan | 106 | 367 | 28% | | atan2 | 167 | 782 | 21% | | exp | 463 | 2722 | 17% | | fract | 166 | 154 | 107% | | hypot | 67 | 203 | 33% | | ln | 196 | 4892 | 4% | | powf | 701 | 9167 | 7% | | round | 129 | 171 | 75% | | sin | 125 | 1237 | 10% | | sqrt | 57 | 57 | 100% | | tan | 138 | 1137 | 12% | | trunc | 57 | 57 | 100% |
