Absolute values for a long long integer

hemcreddy — Thu, 17 Apr 2008 09:22:18 GMT

Hello,

Could someone tell me how to get absolute value for a 64-bit integer on HP-UX 11.23 IA? I could see "long int labs(long int i)" @ http://docs.hp.com/en/B3921-60631/abs.3C.html for a 32-bit integer.

Sizeof(int) & sizeof(long int) print 4 and sizeof(long long int) & sizeof(int64_t) print 8 on my machine.

# aCC -V
aCC: HP aC++/ANSI C B3910B A.06.00 [Aug 25 2004]

Thanks,
Hem

You do it the old fashion way, with inline code:
long long ll1 = -1LL;
long long ll2 = ll1 < 0LL ? -ll1 : ll1;
If you are on 11.31, llabs(3) exists.
