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 |
F_SQRT3 | D_SQRT3 | LD_SQRT3 | Theodorus’ constant, the square root of 3 |
F_SQRT1_2 | D_SQRT1_2 | LD_SQRT1_2 | the square root of 1/2 |
