Domain-specific

• Gamma Function
  • Lanczos-type approximations are widely used, but an implementation must declare accuracy, overflow behavior, complex branch convention, and handling near poles.
• Lanczos Approximation
  • For fixed precision, evaluation then requires a small number of arithmetic operations plus elementary functions.

Verification

Does it exist? Confirmed. This work's DOI resolves to a registered record, which fixes its identity. That is all it fixes.

Does it back the claim? Not recorded. Neither this nor any other of the 2 citations of this work carries a recorded support check.

Support is checked per citation rather than per work — the same source can be cited soundly in one article and wrongly in another. Per-citation recording began recently, so a citation with no recorded check is a gap in the record rather than evidence it went unchecked.
