Re: [amibroker] String problem or what am I doing wrong ?

["Ton Sieverding" <ton.sieverding@xxxxxxxxxx>]

Thanks Tomasz. Yes I understand that the 32bit standard has it's limitations. But why am I getting correct answers for all other values ? Why is just '1' giving me a problem ? Has this to do with precision and will I always get a zero for '1' where other values give me the correct result ? Because that's what I see but do not understand. If I should have a proper answer for that, it's rather simple to modify the result accordingly with string manipulation ...

 

Problem with DateNum() for me is the difference in result before and after 2000. After 2000 gives me '1YY' etc. before 2000 'YY' ... So 2004 becomes '104'. For 1950 I am getting '50' ... Of course there is a solution for that also ...

 

Regards, Ton.

All numbers in AB are industry standard 32-bit FLOATING point
which gives you 7 significant digits.

See "Range and Precision table" here:
http://en.wikipedia.org/wiki/IEEE_754-1985

So you should use
YYYMMDD encoding instead (the same as DateNum() is using)
