Name of contribution: ionumbers Author's name: Christian Schneider Location on CTAN: /macros/latex/contrib/ionumbers Summary description: Bugfix release License type: gpl
Announcement text: ---------------------------------------------------------------------- This release is a bugfix release.
Robert N{u}rnberg reported two problems in ionumbers v0.2.1-alpha: 1. compilation of code like $a^0$ or $sqrt 2$ will fail, if the digit (or sign/point/comma) is not grouped in curly braces 2. the operatorname macro of amsmath/amsopn leads to an error in combination with ionumbers
In the current release (v0.2.3-alpha) the following fixes are included: 1. by adding a special handling of the first character of a number an ungrouped single digit or sign will no longer lead to a failure (similar to the ziffer.sty package, point and comma will still lead to a failure in these (rare) cases from the examples above; this is documented) 2. a warning message is added for the case that amsmath/amsopn is loaded; as a workaround the ionumbers package should be loaded as last package (as already suggested) and the operatorname macro should be used in ionumbersoff (this is documented); this problem is a result of amsopn's strategy of saving the standard mathcode of - and can hardly be fixed in ionumbers (amsopn together with ziffer.sty leads to the same error) 3. the ionumbers_test file contains a lot of different input with the output and expected output of ionumbers for different package options; this makes it easier to test ionumbers especially after changes
Thanks a lot to Robert for his bug reports! ----------------------------------------------------------------------
