Re: [amibroker] Amibroker calculation error

[Herman <psytek@xxxxxxxx>]

Why not use this:

Filter = 1;

SetOption("NoDefaultcolumns",False);

DateNumber = ParamDate("Date",Now(1)); // To provice test DateNum

DateString = NumToStr(DateTimeConvert( 2, DateNumber),formatDateTime);

AddTextColumn(DateString, "DateNum");

Buy = 1;

I am trying to convert a date number to a year+month+day number for better display. It worked before, but for May 11, I got this error: 1070511 + 19000000 = 20070512 instead of 20070511. Here is a piece of code to demonstrate this calculation error:   --------------------------------------------------------- filter = 1; daten = StrFormat("%f", 1070511 + 19000000); AddTextColumn(daten, "DateNum"); buy = 1; --------------------------------------------------------- The column will display 20070512.00000, not 20070511 as you would expect. I understand that in AFL, all numbers are in double type and integer is converted when used. However, this doesn’t seem to be a rounding error since the result is exactly 20070512.00000, not something like 20070511.71332.   I am using 4.90.5.  Have anyone seen this before?   Thanks,   - Mark
