Hex converting

[Andre_Pretorius]

Thanks

This is how I hot it working, you were right about the A being 65

HEXConvert:
IF DATAA = 65 THEN
	DATAA = 10
	RETURN
ENDIF
IF DATAA = 66 THEN
	DATAA = 11
	RETURN
ENDIF
IF DATAA = 67 THEN
	DATAA = 12
	RETURN
ENDIF
IF DATAA = 68 THEN
	DATAA = 13
	RETURN
ENDIF
IF DATAA = 69 THEN
	DATAA = 14
	RETURN
ENDIF
IF DATAA = 70 THEN
	DATAA = 15
	RETURN
else
	DATAA = DATAA - 48
ENDIF

RETURN

Hmm, some people still like spaggeti much more!

Hope at least there is a good salsa with it...

If you're sure your data really just consists of the digits and letters A through F, use this instead. Including comments will help when you come back to it later too.

' This works because 0 - 9 have decimal codes 48 - 57 and A - F have 
' decimal codes 65 - 70 in ASCII
HEXConvert:
IF DATAA >= 65 THEN
	DATAA = DATAA - 55 ' 65 - 55 = 10, 66 - 55 = 11 etc
else
	DATAA = DATAA - 48 ' 48 - 48 = 0, 49 - 48 = 2 etc
ENDIF

RETURN

Thank you tried the new code and works like a charm

eg. 07D9 is what i am getting it must become a year number 2009

An algoritm to convert Hex to Dec is as follows:

Hex 07D9 = 9x16^0 + 13x16^1 + 7x16^2 + 0x16^3 = Dec 2009

I don't see how you achieve the convertion with your system!

I'm sure he's using the partial algorithm he gave to get the 13 from the D for example and then plugging it into another equation like yours.

Of course 49 - 48 <> 2 . Luckily it was in the comments but still...
