u16 FX_Atan2Idx( fx32 y, fx32 x );
y | An fx32 format fixed-point decimal. |
x | An fx32 format fixed-point decimal. |
Arctangent of y/x
This finds the arctangent of y
/x
. The results are returned in a u16
format. The units of the result are equal to 1/65536 of a circle (2 π radians). (Example: A right angle would be 16384.) Internally, a table is referenced.
