Hi
I connect 4002 to MobiFlight for display ALT and Speed param.
But i cant fin procedure of rounding
For example:
Current speed 353, i want see 350 - last digit should be round
what i will do?
Thanks

Hi
If this is a example.... Then its a bad example
I hope you not like to do this.... Make no sense to round a Speed to fully 10 knots up and down!

It´s also a special situation cause you try to round a Full number, but the rounding logic in code is build to round decimal numbers . In your example it is needed to divide the Full number at first to get a decimal that we could round. Finaly you multiply the result again to get the old format back.
like 353 / 10 = 35,3 ------ 35,3 rounded is 35 --------- 35*10=350

So hopefully this was just a "bad" example, I will now explane the normal rounding we use if the value is decimal.


SYNTAX: Round(Value,Number of decimals) e.g. Round($,2) This will round the current Config Value ($) to a number with 2 decimals .
For example $= 123,5251 Here Round($,2) result in 123,53 ...... If you use Round($,1) it result in 123,5 ....... Finaly Round($,0) result in 124 ( No decimals)

NOTE: Its important to use "Round" a big "R" and a small "ound" ........... "round" or "ROUND" will occure in a Error. Also get sure you use a decimal.... not a point !


At Last to awnser the initial example question ( whatever senseless) To get 350 from 353 you use Round($/10,0)*10

thanks for example , it was vary helpful
were i can look on full MobiFlight SYNTAX?

Hi again.

Badly the Syntax is a external Library..... The Documentation is verry poor.

If you got basic knwoledge aboit c# or other rudimentary programming languages then most is self explaned.
