--- Comment #10 from Thomas Henlich <thenlich at users dot sourceforge.net> 2011-04-30 15:56:35 UTC --- The start to scan is the digit corresponding to d+1. e.g. PRINT "(RU,F0.4)", .162500000000000048148 -> .1626 because 00000000000048148 > 0 PRINT "(RU,F0.4)", 3.1415926536 -> 3.1416 because 926536 > 0 PRINT "(RU,F0.1)", 2.5000000000 -> 2.5 because 000000000 = 0
