_Q16 _Q16atan(_Q16 x);
x
ranges from -2147483648 to 2147483647.
This function returns the arc tangent of x in Q16 format. This value
ranges from -2147483648 to 2147483647.
This function finds the arc tangent of a Q16 value and then divides by
PI (π).
<libq.h>
_Q16 _Q16atanByPI(_Q16 x);
x
ranges from -2147483648 to 2147483647.
This function returns the arc tangent of x, divided by PI, in Q16 format.
This value ranges from -2147483648 to 2147483647.
This function finds the arc tangent of y divided by x.
<libq.h>
_Q16 _Q16atanYByX(_Q16 x, _Q16 y);
x
ranges from -2147483648 to 2147483647. This forms the x input.
y
ranges from -2147483648 to 2147483647. This forms the y input.
This function returns the arc tangent of y divided by x in Q16 format.
This value ranges from -2147483648 to 2147483647.
This function finds the arc tangent of the 32-bit input y divided by x and
then divides by PI (π).
<libq.h>
_Q16 _Q16atanYByXByPI(_Q16 x, _Q16 y);
x
ranges from -2147483648 to 2147483647. This forms the x input.
y
ranges from -2147483648 to 2147483647. This forms the y input.
This function returns the arc tangent y divided by x, divided by PI, in
Q16 format. This value ranges from -2147483648 to 2147483647.
