From: Keith Browne <tuxedo <at> htq.org> To: bug-gnu-emacs <at> gnu.org Subject: 23.2; Improper integer conversion (rounding?) on data entry in Calc Date: Tue, 30 Aug 2011 17:35:33 -0400 (EDT)
M-x calc [RETURN] 90000000000000010 [RETURN] (that's 9, followed by fourteen 0s, followed by 10) - Observe that 90000000000000016 appears on the stack, not 90000000000000010. This appears to be occurring for a bunch of different values, starting somewhere below 20000000000000000 and running up through 900000000000000000 or higher. It's occurring whether I type the values by hand, or cut and paste through a window manager. It's even happening if I enter the value correctly in a different Emacs buffer and then cut and yank it into the Calc buffer. I've tested this on a variety of machines and versions of Emacs. Some work, some don't. For instance, a powerpc-unknown-linux-gnu machine running Emacs 23.3.1 is working, while an x86_64-apple-darwin10.8.0 machine running Emacs 23.3.1 is broken. It could be a problem with the compiler toolchain that built the various Emacsen. Since identical versions of Emacs are either succeeding or failing on different machines, it's unlikely to be a regression in Emacs or in Calc. Could it be that some machines are allowing the conversion to pass through floating-point and back to int, resulting in a rounding error?

That is an inaccuracy in string-to-number that should be fixed in Emacs 24. You can work around it by reducing math-bignum-digit-length.

I've confirmed that this bug is fixed in the Emacs trunk and am marking it as done.
