--- Comment #12 from drking <[email protected]> --- The current Gnumeric code says: * Original source of the following functions (ScGetGDA, ScInterVDB, and * get_vdb) is the OpenOffice version 1.0, `sc/source/core/tool/interpr2.cxx'. * * RCSfile: interpr2.cxx,v * * Revision: 1.11 * * last change: Author: er Date: 2001/03/15 21:31:13 In other words they borrowed from OpenOffice. The function is fine with whole number periods I think - so my inclination would be to leave it in, and try to understand the IRS system, which must be what Excel based it on. The fact that they don't document it with fractional periods, means that no-one can trust their function either. Sigh. -- You are receiving this mail because: You are on the CC list for the issue.
