xnumbersとは 意味・読み方・使い方

XNUMBERS is a multi-precision floating point computing and numerical methods library for Microsoft Excel. Xnumbers is an open source Excel addin (xla) that performs multi-precision floating point arithmetic from 15 up to 200 significant digits. The version 5.6 as of 2008 is compatible with Excel 2003/XP and consists of a set of more than 300 functions for arithmetic, complex, trigonometric, logarithm, exponential calculus. Unfortunately, the Foxes team members (around Leonardo Volpi) have stopped their developmental efforts in 2008. Recently, an American astronomer had his brother John Beyers made the Italian versions compatible to recent versions of Microsoft Excel/Windows/VisualBasic. Several forked versions are made available in the last section of the astronomer's homepage, entitled "Downloads and links".
