Subject [jira] Commented: (STDCXX-640) std::num_get::do_get() parses no more than 128 characters
Date Thu, 03 Apr 2008 19:41:24 GMT

    [ https://issues.apache.org/jira/browse/STDCXX-640?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12585254#action_12585254

Martin Sebor commented on STDCXX-640:
-------------------------------------

That depends if it's being parsed as an integer or floating point number. If the former, it
should be 10, otherwise 1.
