Hi!
----
Another bug we hit today in ast-ksh.2008-02-02 when developing an
application:
It seems that ksh93 has problems with the sign then converting something
like "Inf" (floating-point Infinite) to an integer variable.
Example:
-- snip --
$ ksh93 -c 'integer x=+Inf ; printf "%d\n" x'
-9223372036854775808
$ ksh93 -c 'integer x ; (( x=+Inf )) ; printf "%d\n" x'
-9223372036854775808
-- snip --
... AFAIK "x" should have a positive sign, e.g. the following C99 test
case...
-- snip --
#include <stdlib.h>
#include <stdio.h>
#include <limits.h>
#include <math.h>
int main(int ac, char *av[])
{
long double fp;
long long i;
fp=INFINITY;
i=fp;
printf("fp=%Lf\n", fp);
printf("i=%lld\n", i);
return EXIT_SUCCESS;
}
-- snip --
...returns:
-- snip --
$ cc -xc99=%all c99_float_infinity_to_int.c
$ ./a.out
fp=inf
i=9223372036854775807
-- snip --

bye,
