This package provides a JavaScript implementation of the incomplete gamma function, which computes the regularized lower incomplete gamma function by default. It can also evaluate the upper incomplete gamma function or the unregularized versions based on optional parameters. The function is primarily intended for use in scientific and numerical computing applications that require advanced mathematical functions.
