gMath_QuadrantSin
const s32 gMath_QuadrantSin[4]
The sine at 0, 90, 180 and 270 degrees, in Q16.
Definition math_table.c:48
gMath_TanTable
const u16 gMath_TanTable[258]
Tangents scaled by 256: index i is tan(i * 45 / 128 degrees), so index 128 is tan(45 degrees).

gMath_TwoPiSteps
const u16 gMath_TwoPiSteps[8]
floor(i * 2π)
Definition math_table.c:43
gMath_SinQuarter
const u16 gMath_SinQuarter[256]
A quarter-wave sine table, scaled by 65536.
