Macro for defininge fix16_quat_t constant values.

Note

The argument is evaluated multiple times, and also otherwise you should only use this for constant values. For runtime-conversions, use the inlined functions below.

Parameters

w	The constant value.
x	The constant value.
y	The constant value.
z	The constant value.
