calculate var Byte's and var Word's

[Pedro Pinto]

Hello All

I need to calculate this example:

varWord = (varByteA*365) + (varByteB*30) + (varByteC/2) + varByteD

The PIC calculate always varWord = 0

How can I write this, or must I before calculate copy the var's byte's in word's, like so

varWordA = varByteA:varWordB = varByteB:varWordC = varByteC:varWordD = varByteD

varWord = (varWordA*365) + (varWordB*30) + (varWordBC/2) + varWordD



Thank for any help

Best Regards

Pedro

If varByteC is not a multiple of 2, then the result is a floating point, which pbp doesnt support. Also, your word result can be no higher than 65535.

Hi,

what I mean is:

c var byte
b var byte
a var word

c=12
b=34

a=c*b

Is this correct, or must the var a and b be word var

Thanks

Hi,

sorry,

Is this correct, or must the var b and c be word var?

Only variables whose content is likely to exceed 8 bits need to be WORDS.

In your example 'a' MUST be a WORD, 'b' and 'c' need not be.
