What does Intel IPP status -51 (ippStsDivisorErr) mean?

ippStsDivisorErr

This status is an error-path form of division-by-zero handling: the divisor value is zero and the function stops rather than producing a saturated, infinite or warning-only result.

Use the exact primitive documentation to decide whether zero divisors should be rejected, masked, replaced or handled with a threshold operation before the IPP call.

Check these details

• Scalar divisor and per-element divisor arrays.
• Whether integer and floating-point variants have different zero-handling rules.
• Prevalidation or mask logic that should exclude zero divisor elements.
