To enable this property for fixed-point types, set Function as sin , cos, sincos , cos+jsin, or atan2 and Approximation method as CORDIC. Specify whether to map the blocks in your design to MAX , CUSTOM, or ZERO latency for fixed-point and floating-point types. The default is MAX.

WebThe standard name for a two-argument arctan is atan2(), so I'll use that name as well. As a division of the two coordinates is involved, the position of the fixed point is actually not important, but let's take it as 12, so that 1.0 corresponds to 0x1000. The return value is an integer with a 2π range.
