DEV: allsky_overlay.py - Format a number

Hi Alex,

I had a problem with the formatting of a Number field. For example, I tried the following formats for ${MEAN} in the overlay editor:

Test with %.2f

Line 698, format = format.replace("%", "{:.") + "}"
Result for format: {:..2f}

Test with {:.2f}
Result format: {:.2f}}

For us Germans, there is also the fact that the decimal separator may be a comma. I have adapted the function like this. Not much tested, the syntax can certainly be adapted (only the principle):

                if variableType == 'Number':
                    if format is not None and format != "":
                        if "%" in format:
                            format = format.replace("%", "{:") + "}"
                        comma = ("," in value)
                        if comma:
                            value = value.replace(",", ".")
                        ''' We allow text to be substituded for numbers so if the conversion to a flot
                        fails we will just return the value for the field.
                        '''                    
                        try:
                            value = s.float(value)
                            value = format.format(value)
                        except ValueError:
                            pass
                        if comma:
                            value = value.replace(".", ",")

I am currently changing the formatting code to use standard python formats. This includes locale formats so using a comma as a decimal separator will be fine. This will be available in the next release
