I am using a NxSpinEdit control to display a float value with Precision = 0. If I assign a non-integer value to the control (for example 1.11), the control shows 1.11 instead of 1. If Precision is non-zero, the value is displayed with the correct Precision. I have not found a workaround.

Hello Phyllis,
Please set eoAllowFloat in Options property to False.
I didn't predict situations when eoAllowFloat = True, and Precision = 0 which is equal to eoAllowFloat = False. I will fix this now.
Best regards

I changed the eoAllowFloat option but that changes the Value property of the control. For example, value = 30.16, set eoAllowFloat = false, Value = 3016. I need the Value to remain 30.16 but the Text to become '30'.
Here is an example of what I am doing:
Suppose the control shows air pressure. For Metric Units mode, pressure is shown in millibars; for English Units mode, it is shown in hundredths on inches. In either case I want the underlying value to be kept as a double to minimize rounding errors. So when showing millibars, I want a double value displayed with 0 decimal digits and rounded; when showing inches, I want a double value displayed with two decimal digits and rounded.
Is this simply 'not as designed'?
Thanks in advance,
- Phyllis

Hi Phyllis
Have you tried using the FormatMask? (e.g "0.00" for two decimals etc)

Deon

Oops. Please ignore my last post.
I did not read your first post. NxSpinEdit does not have a FormatMask
I thought you were using a grid.
Sorry..

Hello Phyllis,
Unfortunatelly, Value is float representation of Text property. When you check Value property, text in Text property is converted (and validated for non-numbers) to float. There is no rounding, only slicing.
I have fix Precision problem and I may send you new NxEdit.pas file to you.

Hello,
I have made it to work in following way.
If eoAllowFloat is False, Precision is ignored, and it is actualy 0 (Decimal separator can't be typed).
If eoAllowFloat is True, Precision is used if Precision > 0. If Precision is 0, it is ignored.
Best regards

That sounds great. If you can send the source file I'll try it and see if this can work in my situation.
Thanks!
