Why does
sprintf( '%.03f', 0.15250000 )
return 0.152 while
sprintf( '%.03f', 0.15750000 )
return 0.158?
The 4th significant digit in both cases is '5' but in the first case, it's
rounded down but in the second case it is rounded up. Is sprintf() basing
it's decision on the value of the 3rd significant digit? If so, why?
Shouldn't rounding decisions be based on subsequent digits and not preceding
ones?
I am using PHP 4.3.11
thnx,
Christoph
