Bit conversion

[lerameur]

PBP do not take signed intergers

[HenrikOlsson]

Lerameur,

Multiplications with negative numbers works but if you need division you need to do a little "manual" work:

Sign VAR Word       'This will hold the sign of our value.
Left VAR Word
Right VAR Word
Temp VAR Word

Left = 100
Right = 200

Temp = Left - Right     'Temp is now -100 (or 65436)

If Temp.15 = 1 then    'Highest bit set means value is negative
   Sign = -1
Else
   Sign = 1
Endif

'We cant divide a negative number so we have to use the ABS operator.
Temp = ABS(Temp) / 2    'Temp is now 50 (positve)

Temp = Temp * Sign       'Re-apply sign, Temp is now -50 (or 65486)

hi Henrik,

I am not sure how lerameur will implement this information into his problem.

Hi Sayzer,
He said PBP don't 'take' signed integers and I showed him a way to get around it. I guess I didn't understand the problem, still don't then....

Sorry if I made more confusing.

NP Henrik,

His problem is with floating point issue that PBP does not support.

As you said he still needs to do some manual work.



He will take care of his problem with a few more code lines.
