🧮 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%
