bit swap from c to PB

[supercdfr]

i have this in c :

Code: Select all

printf("%u\n\n\n",(3967115105 << 28) | (3967115105 >> 4) )

And i have the result : 516380150 that is correct

When i try whit PB, i have this :

Code: Select all

Debug (3967115105 << 28) | (3967115105 >> 4)

i have 1064914352463107574 that is incorrect.

I try stru, strd strf, but the result is always false.

To obtain a long integer you have to remove all unwanted digits with an AND $FFFFFFFF operation. The following code line therefore displays your wanted result:

Code: Select all

Debug ((3967115105 << 28) | (3967115105 >> 4)) & $FFFFFFFF ; Displays 516380150
