| Summary | 0000942: Simple numeric comparison fails with "binary" and "decimal" numersystems | ||||
| Description | Consider this program: show 0.0001 < 0.001, numbersystem, mpversion; end. With the default number system this gives >> true >> "scaled" >> "1.999" ) on my log. But with the other number systems I get: >> true >> "double" >> "1.999" ) >> false >> "binary" >> "1.999" ) >> false >> "decimal" >> "1.999" ) which is a bit unexpected... I'm using a version I compiled myself from source after you fixed the normaldeviate bug a couple of months ago. | ||||
| Steps To Reproduce | Run show 0.0001 < 0.001, numbersystem, mpversion; end. with the 4 different number systems. | ||||
| Tags | No tags attached. | ||||

Testing with V1.902 (the only other version I have on hand, I only get the error with "decimal". But it does not appear to matter what numbers I use (ie same bug with 1<2, or 1/4<1/2, etc This is MetaPost, version 1.902 (TeX Live 2014) (kpathsea version 6.2.0) >> true >> "scaled" ) This is MetaPost, version 1.902 (TeX Live 2014) (kpathsea version 6.2.0) >> true >> "double" ) This is MetaPost, version 1.902 (TeX Live 2014) (kpathsea version 6.2.0) >> true >> "binary" ) This is MetaPost, version 1.902 (TeX Live 2014) (kpathsea version 6.2.0) >> false >> "decimal" ) |

It should be fixed in trunk. |

Thanks - looks good from here. Can you share any details about where the bug was? |

IIRC, it should be a patch from Akira. See "better patch for to_boolean for decimal and binary number system (A. Kakuto)" in the svn repo. |
