Subject: [OASIS Issue Tracker] (OFFICE-4005) Remove "non-negative integer" constraint from BESSELJ function
Regina Henschel created OFFICE-4005: --------------------------------------- Summary: Remove "non-negative integer" constraint from BESSELJ function Key: OFFICE-4005 URL: https://issues.oasis-open.org/browse/OFFICE-4005 Project: OASIS Open Document Format for Office Applications (OpenDocument) TC Issue Type: Improvement Components: OpenFormula Reporter: Regina Henschel The BESSELJ function ( section 6.16.13 in ODF1.3 draft) has the Constraints "N >= 0, INT(N)=N; Evaluators may evaluate expressions where N >= 0 returns a non-error value." But the order N need not be non-negative, there exists reflection formulae. And the order N need not be integer, fractional order, especially half-integer is used too.
