How to get normalized double to always display 1 decimal point?

 

I'm currently using NormalizeDouble() to edit the precision of a calculation to 1 decimal point. I'm displaying this number on my chart. Most of the time it displays as e.g. 10.1 or 10.6, but when it calculates as a whole integer the visual spacing changes momentarily.

How can I get this number to display as e.g. 10.0 instead of 10?

 
Read the documentation on PrintFormat and StringFormat.
 

Example:

PrintFormat( "%.1f", 10 ); // -> 10.0

Thanks for the example. I’d been looking at the documentation for these functions, and trying them out, with no success.

I’ll give this a go and look at the documentation again with it.
 

You used NormalizeDouble, It's use is usually wrong, as it is in your case.

  1. Floating point has an infinite number of decimals, it's you were not understanding floating point and that some numbers can't be represented exactly. (like 1/10.)

  2. Print out your values to the precision you want with DoubleToString - Conversion Functions - MQL4 Reference.

  3. SL/TP (stops) need to be normalized to tick size (not Point) — code fails on non-currencies.

  4. Open price for pending orders need to be adjusted. On Currencies, Point == TickSize, so you will get the same answer, but it won't work on non-currencies. So do it right.

  5. Lot size must also be adjusted to a multiple of LotStep and check against min and max. If that is not a power of 1/10 then NormalizeDouble is wrong. Do it right.

  6. MathRound() and NormalizeDouble() are rounding in a different way. Make it explicit.

  7. Prices you get from the terminal are already correct (normalized).

  8. PIP, Point, or Tick are all different in general.
