Number Precision
number-precision is a JavaScript math library and arbitrary precision arithmetic utility. It provides a set of functions for performing addition, subtraction, multiplication, and division while avoiding the rounding errors common in standard binary floating-point operations.
The project focuses on maintaining controlled decimal precision to ensure consistent mathematical output. This makes it applicable for financial calculations where exact currency values are required, as well as for high precision data processing in scientific or technical reports.
Its capabilities include precise floating-point arithmetic and numeric data normalization through the rounding of values to specific decimal precisions.
