Approximation Packages

A library to perform function approximation.

Converts a decimal number using fixed-point notation, avoiding the conversion from number to string of Number.toFixed, and allowing the user to choose the approximation method to be used

trigonometric approximations

Arbitrary-precision decimals. Enables making math calculations with rational numbers, without precision loss.

Incomplete gamma function.

Inverse incomplete gamma function.

Calculate the Lanczos sum for the approximation of the gamma function.

Calculate a scaled Lanczos sum for the approximation of the gamma function.

Incomplete gamma function.

Inverse incomplete gamma function.

Incomplete beta function and its first derivative.

Inverse incomplete beta function.

Compute an integer binary logarithm (base two).

Compute an integer square root.

Compute the hypotenuse using the alpha max plus beta min algorithm.

Incomplete beta function.

Inverse incomplete beta function.

Arbitrary constant `g` to be used in Lanczos approximation functions.

Evaluate the terms of a continued fraction.
