ippStsEpsValErr

Epsilon parameters normally express tolerance, convergence threshold or comparison slack. A negative epsilon reverses that meaning and cannot define a valid nonnegative tolerance band.

This often appears when configuration values are loaded without validation or when a caller uses a sentinel such as -1 for automatic tolerance even though the function does not accept it.

Check these details

  • The tolerance or epsilon argument after parsing configuration.
  • Whether the routine expects absolute, relative or squared tolerance.
  • Default-value handling for automatic tolerance selection.
