Math Function Library

A math function library for various programming languages. The primary target is WebAssembly, everything else is secondary and may not be stable. Use at your own risk.

Note: This library is not yet in a stable state. Exponent function cannot calculate with decimals powers (which results in root function not working yet either)

Supported Languages

• C
• C++
• WebAssembly
  • JavaScript (with proper .wasm import)
  • TypeScript (with proper .wasm import)

Supported Operations

The following functions are provided:

• add(a, b) - Calculates the sum of values a & b

• subtract(a, b) - Calculates the difference of b subtracted from a

• multiply(a, b) - Calculates the product of values a & b

• divide(a, b) - Calculates the quotient of a divided by b

• one_over(a) - Calculates the quotient of 1 divided by a

• percent(a, percent) - Calculates the percent of value a

• is_whole_num(a) - Returns whether or not a is a whole number

• is_even(a) - Returns whether or not a is an even number

• am(a, b) - Calculates the Arithmetic Mean of provided values a & b

• gm(a, b) - Calculates the Geometric Mean of provided values a & b

• agm(a, b) - Calculates the Arithmetic-Geometric Mean of a and b

• sq_root(a) - Calculates the square root of a

• ln(a) - Calculates the natural log of a using the formula in formulas/natural-log.odf. This file can be opened w/ LibreOffice Math

  • Note: The results returned from this function will start to lose precision around the hundred thousandths decimal place.

• log(base, arguement) - Calculates the logarithm of base & arguement

• exponent(base, exponent) - Calculates the value of base to the exponent power

  • Note: This only works when the exponent is a whole number (currently)

• root(index, radicand) - Calculates the value of index to the root of radicand

Building

mathfun.c

Emscripten is required to compile this project to WebAssembly.

Run either of the following commands to compile calculator.c to calculator.wasm

# Make Command:
make

# Build Command:
emcc -Os mathfun.c -o mathfun.wasm --no-entry

mathfun.wat

This file is generated from a compiled version of calculator.wasm. It is provided so anyone can compile the .wasm file from it without the need for emscripten.
