String conversion from Double not working correctly
-
I am dealin with this now for quite some time and now I acutally would like to ask for your support. There is an issue, that was mentioned by the way several times now in this forum, that Doubles are not converted correctly to Strings. It works 90% of the time, but then 10% it does not work. As I am using mql code directly, the issue must be produced by fxdreema.
I used following code lines and all of them produce the same results:
printProfit = DoubleToStr(AccountProfit(), 2);
printProfit = DoubleToString(AccountProfit(), 2);
printProfit = NormalizeDouble(AccountProfit(), 2);
printProfit = StringSubstr(printProfit, 0, StringFind(printProfit, ".", 0) +3);It would be great if that issue could be resolved, as this messes up the text on charts and buttons.
Thank you

@MMBInvest it is a common issue with mql language itself, I think it would happen if you coded the whole thing in Metaeditor. https://www.forexfactory.com/thread/1190602-rounding-in-mql4
NormalizeDouble often fails to cut the digits, but DoubleToString does work for me 100%.
Can you show some example case in shared link? -
Ok, in this case I take back the fxdreema blaming ;o) - it is not working however, and it super annoying, because you cannot use this functions ...
-
The example doesn't compile, but I assume the printProfit is a string variable
-
Yes, it is just the part where the function is used ... I can make it compileable ... this one compiles now: https://fxdreema.com/shared/OtJ389D1d

Its difficult to reproduce the bug with this, even when making it backtestable: https://fxdreema.com/shared/hPqJMbjyb
Can you find some number that produces the infinite zeroes with StringToDouble?
-
So, now if I use the same code for pure mql4 and for fxdreema, I don't get the issue with the pure code (see attached example code) whilst fxdreema will created this long numbers ... but again, not always, it is ok for a minute and then it shows the long numbers once or twice, and then it is ok again, still it is annoying not useable that way... no work-around is working (!) EVEN if I convert everything in strings and then use string functions to build something useable ... the same behaviour... I mean, a string has nothing to do with the number conversions, and it is still not working.

The video shows the problem ... how its working until there is a glitch ... so I will remove this and don't use it anymore.

@MMBInvest DoubleToString() always works, I dont know what else to say. Here is an example you can actually reproduce, maybe it helps.
