This repository contains C code for generating fixed-point lookup tables for the sine, cosine, and negative inverse tangent functions. The lookup tables are generated using floating-point arithmetic and then converted to fixed-point format.

To use the code, simply run the main function of the program. This will generate three lookup tables for the sine, cosine, and negative inverse tangent functions, respectively. The lookup tables will be written to a C header file, which can be included in your C project.

The generateLUT function takes four arguments:

void generateLUT(const char* name, int values, int fixedpoint_decimals, const char* file_name)

• name: A string containing the name of the lookup table.
• values: An integer specifying the number of values in the lookup table.
• fixedpoint_decimals: An integer specifying the number of decimal places in the fixed-point format. For example, a value of 16 would create a fixed-point format with 16 bits for the integer part and 16 bits for the fractional part.
• file_name: A string containing the name of the output file.

The code requires the following C libraries:

• stdio.h
• stdlib.h
• string.h
• stdint.h
• math.h
