Title: Hexadecimal to Decimal
Post by: Breidy on September 10, 2021, 02:31:10 PM

Hi everyone
I have a question

This formula returns me the decimal number

Excel
HEX2DEC ("8FCB455C") = 2412463452
HEX2DEC ("7FA2478E") = 2141341582

PxPlus
DEC (ATH ("8FCB455C") = -1882503844
DEC (ATH ("7FA2478E") = 2141341582

Why does pxplus return the decimal value of the first data differently?

Could someone guide me please

As with most computer systems the top (first) bit indicates the sign of the value thus $8FCB455C$ would be a negative number.

If you want to force the value positive regardless of the number of bytes, prefix the value with $00$.

->print DEC (ATH ("008FCB455C") )
 2412463452
->print DEC ($00$ + ATH ("8FCB455C") )
 2412463452
