Bug with DoubleToString

[GSMtricks]

Hi, I used DoubleToString(trading_amount_initial,2) for making numbers like 12.11 (for example)
The problem is that numbers still in format 12.11111111111111
Sometimes they are ok, but sometimes like i wrote above.

Does it happen in mq5?

[GSMtricks]

Yes, I don't know why this happens. Check all, but still sometimes after compiling it works as needed, and most times - as described above.

I know mq5 for fxDreema is not as efficiently implementes as for mq4. Maybe it's a bug. Unfortunately I'm not a programmer so I cannot give you an answer.

Maybe it helps to use MathFloor in combination with the DoubleToString?

@roar Don't understand what do you mean ;(
All that do I need to have just 2 digits after the DOT. No like 12.19999999999 - need just 12.19 that all.

@gsmtricks
MathFloor(12.19999999999 * 100) / 100
^^ This should return 12.19

@roar Cool.
Could you give me an example if 12.19999999999 have in variable named for example: Rate

Thank you.

@gsmtricks Just replace it to the function:
MathFloor(Rate * 100) / 100

Hope it works!
