XMATH_BFP_DEBUG_CHECK_LENGTHS

Indicates whether the BFP functions should check vector lengths for errors.

Iff true, BFP functions will check (assert()) to ensure that each BFP vector argument does not violate any length constraints. Most often this simply ensures that, where BFP functions take multiple vectors as parameters, each of the vectors has the same length.

Defaults to false (0).

XMATH_BFP_SQRT_DEPTH_S16

The number of most significant bits which are computed by bfp_s16_sqrt().

The function bfp_sqrt_s16() computes results one bit at a time, starting with bit 14 (the second-to-most significant bit). Because this is a relatively expensive operation, it may be desirable to trade off precision of results for a speed-up.

The time cost of bfp_sqrt_s16() is approximately linear with respect to the depth.

Defaults to VECT_SQRT_S16_MAX_DEPTH (15)

XMATH_BFP_SQRT_DEPTH_S32

The number of most significant bits which are computed by bfp_s32_sqrt().

The function bfp_sqrt_s32() computes results one bit at a time, starting with bit 30 (the second-to-most significant bit). Because this is a relatively expensive operation, it may be desirable to trade off precision of results for a speed-up.

The time cost of bfp_sqrt_s32() is approximately linear with respect to the depth.

Defaults to VECT_SQRT_S32_MAX_DEPTH (31)
