https://issues.dlang.org/show_bug.cgi?id=12813 Issue ID: 12813 Summary: Parser is confused between float and UFC syntax Product: D Version: D2 Hardware: All OS: All Status: NEW Severity: regression Priority: P1 Component: DMD Assignee: nobody puremagic.com Reporter: ibuclaw gdcproject.org According to the docs (lex) """ Floating literals can have embedded ‘_’ characters, which are ignored. The embedded ‘_’ are useful for formatting long literals to make them more readable, such as using them as a thousands separator """ And the following examples are given as valid. 123_456.567_8 // 123456.5678 1_2_3_4_5_6_._5_6_7_8 // 123456.5678 1_2_3_4_5_6_._5e-6_ // 123456.5e-6 However: 123_456.567_8 // OK 1_2_3_4_5_6_._5_6_7_8 // ERROR no property '_5_6_7_8' for type 'int' 1_2_3_4_5_6_._5e-6_ // ERROR no property '_5e' for type 'int' Marking as regression because this would have been fine before UFCs. --
