LTRIM & Rounding - how to combine syntax?

[lakeshoretech]

$f15 = 0.345677 (output from sql data pull)

 

<?php echo number_format ($f15,3); ?>

output = 0.345

 

<?php echo ltrim($f15,"0"); number_format ($f15,3); ?>

output = .345677

 

How do I combine these so that I am BOTH rounding the result AND trimming a leading zero?  Seems I can get one or the other, but not both.

 

Suggestions on the syntax?

I am not sure why you would want to, but an inelegant solution would be to use the substr() function to remove the first character if the first character is equal to zero.

s0c0 - ?

 

Why I'd want to what?    You lost me. 

 

Needing my result to be a "batting average" of sorts.    Eliminate zero (but not a 1) before the decimal and round to 3 places.

<?php echo ltrim(number_format ($f15,3),"0"); ; ?>

Thanks.  Perfect.
