Description:
------------
This a followup to bug #48455 which has been closed.
I observed same bug with different values.
I'm affraid rasmus' answer is incorrect.
3498 is represented with 12 bits. A float holds 24 bits which is far
enough to contain 3498 without any single bit of precision loss.
Anyway, the same program in C works fine:
#include <stdio.h>
main()
{
float f;
f=34.98*100;
printf("%6d %f\n",(int)f,f);
}
thus the problem is NOT with the float representation.
Moreover the following script should return twice the same thing:
$x=34.98*100;
print "x:".$x." sprintf:".sprintf('%d',$x);
but the unexpected result is:
x:3498 sprintf:3497
If the first conversion from float to string works fine, why doesn't
the second conversion work ?
