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.

F_PI	D_PI	LD_PI	Archimede’s constant pi
F_PI_2	D_PI_2	LD_PI_2	pi divided by 2
F_PI_3	D_PI_3	LD_PI_3	pi divided by 3
F_PI_4	D_PI_4	LD_PI_4	pi divided by 4
F_1_PI	D_1_PI	LD_1_PI	the reciprocal of pi
F_2_PI	D_2_PI	LD_2_PI	2 divided by pi
F_SQRT2	D_SQRT2	LD_SQRT2	Pythagoras’ constant, the square root of 2
