This header provides some commonly used constants. They are similar to the `M_PI`, `M_E` etc. variables provided by the `` 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 [wiki:doc/lol/math/real.h ] header.
