Hi,
I need to extract the first digit after the decimal point from a number such
as 28.56018, which should be '5'.
I've tried a few methods to accomplish this. If I use 'ini_set' I would need
to know the number of digits before the decimal (which, unfortunately, I
would not have access to).
Then I've tried:
<?php
$elapsed = 28.56018;
$digit = round($elapsed, 1); // rounds result is '6'
$digit = number_format($elapsed, 1); // still rounds result to '6'
?>
What I need is only the first digit after the decimal -- all the rest could
be 'chopped' or discarded but without rounding the first digit after the
decimal point.
Is there any way of doing this?
I'm stumped.
Tia,
Andre
