Aggiornamento di GNUMERIC, versione 1.10

Gnumeric 1.10 è la nuova versione del foglio di calcolo di GNOME. La trovate, insieme al word processor Abiword, nel mio repository https://launchpad.net/~guido-iodice/+archive/abiword-2.8

Il changelog è abbastanza interessante e corposo:

  • Adjustable sheet size: sheets are no longer restricted to 256 columns of 65536 rows.
  • Graphs have been improved. For example:
    • New plot types for surfaces and probability plots.
    • When an axis is a date or time axis, reasonable places for tick marks will be picked.
    • Cubic splines interpolation.
    • Error bars in polar and radar plots.
  • ODF support has been improved. Note, that until and unless the syntax and semantics of ODF files are defined, interoperability between any two implementations will be limited. Five years with no action on that front suggests that it will not happen in the near term. My five years old assessment still applies.
  • Compatibility: we have improved function compatibility with Excel, mostly in border cases. Gnumeric also now supports almost all functions in the OpenFormla large function group. We have different names for a few of them, but remap on load and save from ODF files.
  • New functions are ACOT, ACOTH, ADTEST, ARABIC, ASCENSIONTHURSDAY, ASHWEDNESDAY, AVERAGEIF, BINOM.DIST.RANGE, CHOLESKY, COMBINA, COT, COTH, CSC, CSCH, CVMTEST, DAYS, EASTERSUNDAY, EIGEN, FINDB, FOURIER, GAMMA, GD, GET.LINK, GOODFRIDAY, HDATE, HDATE_DAY, HDATE_HEB, HDATE_JULIAN, HDATE_MONTH, HDATE_YEAR, IFNA, ISFORMULA, JIS, LEFTB, LKSTEST, MIDB, MUNIT, NUMBERVALUE, PENTECOSTSUNDAY, PERMUTATIONA, R.DSNORM, R.DST, R.PSNORM, RANDSNORM, RANDSTDIST, RANK.AVG, REPLACEB, RIGHTB, RRI, SEARCHB, SEC, SFTEST, SHEET, and SHEETS.
  • Faster evaluation: some fairly common sheets with large numbers of calls to the HLOOKUP or similar functions, over the same database have been improved from “rather slow” to “instant”. Similar improvements have been implemented for farms of RANK or PERCENTILE calls.
  • Memory usage for large sheets is significantly down.
  • The statistical analysis tools have been improved and there are quite a few new ones, for example:
    • Kaplan-Meier Estimates.
    • Principal Component Analysis.
    • Normality Tests.
    • Sign Tests.
    • Trend and/or Season Corrected Exponential Smoothing.
  • Support for sheet objects (lines, arrows, widgets, …) has been improved.
  • New utility: ssgrep allows searching collections of spreadsheet files in a manner similar to how grep searches text files.
