always round up or down

[STG82]

Hallo,

I´m looking for a function in DIAdem to always round up or down. I build myself some but they are old and slow... and they also work only almost perfect, some cases Just wont work right.

The aim is to round figures to 1/100, 5/100, 1/10, 5/10, to numbers, X mod 5 = 0, to x mod 10 = 0, to x mod 50 = 0 and so on.

I want to use it for scalling Report-Diagramms automatically, but with fixed and round scales - also for same scales of one meassurement in different Messures.

Therefor i need the funktion to Round Up always or in Minus Round down always.

If someone has a nice Solution for it i would be very thankfull.

Thanks already for ur surport.

I'm not sure I fully understand the question, but hopefully this helps:

Frac = Return decimal portion of a number

Trunc = Return Integer portion of a number

intMyResult = Frac(Pi)    'intMyResult = 0.14159265358979

intMyResult = Trunc(-75.5109) 'intMyResult = -75

So a combination of these could give you:

Always Round Up:

  If Frac(Val) > 0 then MyResult = Trunc(Val) + 1

Example:

  Var =Pi

  If Frac(Var) > 0 then

    MyResult = Trunc(Var) + 1

  Else

    MyResult = Var '4

  end if

Always Round Down:

  MyResult = Trunc(Val)

Example:

  Var =Pi

  MyResult =Trunc(Var) '3

You can also combine this with multiplying&dividing by 10/100/1000 to round to specific numbers of decimal places

Example:

  Var =10.12345

  Var = Var *100

  Var =Trunc(Var)

  Var = Var /100

  MyResult = Var  '10.12

Hi STG,

Check out the DIAdem 2015 Beta version, there is a new "Round Channels" ANALYSIS function in the "Basic Mathematics" palette that should make you happy.
