GAMMA.DIST function - specification of the function: https://support.office.com/en-US/article/GAMMA-DIST-function-9B6F1538-D11C-4D5F-8966-21F6A2201DEF

Remark: If x < 0, GAMMA.DIST returns the #NUM! error value.

On pc Debian x86-64 with master sources updated today, I could reproduce this.

Winfried: one for you?

@Julien: Raal created the bug report after communicating with me; you were faster than I was ;-)

Comment 3 Eike Rathke 2016-10-13 18:14:34 UTC

Actually not inherited from OOo because the GAMMA.DIST function didn't exist back then.. apparently confused with the GAMMADIST function. GAMMA.DIST was introduced with 4.3
