Some questions about formatting and units

[Mark Goossens]

• Is there also a setGroupingSeparator('.') method available?

• Instead of using SIGFIGS(3) as an example, can I set the number of significant digits directly?
  For example, to show values like 540.678,98 and 5.127.658,20

• Could you clarify which SI units are supported and how the system handles them?
  The reference files seem to be inaccessible.
  I primarily use: kN, N, N/mm², where kN equals to 1.000,00 N
  How can I use SI prefixes, like :
  "k" which stands for kilo-, and means 1.000 (10³).
  "c" which stands for centi-, and means 0,01 (10⁻²).
  For example, kN, kg, cm, m, km, mm, ...

• Is it possible to use currency symbols (e.g., €) as units?
  For example, to calculate values like €/m²?

Kind regards,

Mark

I think most of your questions will be answered by demo document:
https://sourceforge.net/p/comppad/repo/ci/Python/tree/test/CompPadDemo.odt

• There is a setThousandsSeparator function for setting the thousands grouping separator that is used in the displayed results.
• For significant figures display, you can use setSigFigs function.
• You can see in the demo document how to apply the units, including how to specify the display units in an expression. For instance, you can evaluate the expression:

x := 1000 m/s = km/hr

evaluates to:

x := 1000 m/s = {{"3 600"`}}km/hr

• I will create a comprehensive list of units soon, but most of the standard SI units work, with the typical prefixes.
• Currency units aren't currently supported. You could just define a currency symbol as 1 and use it in the units for display purposes:

€:=1
500 €/kg = {{"0.5000"`}}€/g
