Table of Contents
This header provides some commonly used constants. They are similar to the M_PI, M_E etc. variables provided by the <math.h> header except they have the F_ prefix for “float”, D_ for “double” and LD_ for “long double”.
List of constants
Note that these constants also exist with increased precision. See the <lol/math/real.h> header.
