Approximation Packages

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

A library to perform function approximation.

trigonometric approximations

Inverse incomplete gamma function.

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

Evaluate the terms of a continued fraction.

Incomplete beta function and its first derivative.

Inverse incomplete beta 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.

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

Compute an integer binary logarithm (base two).

Compute an integer square root.

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