Post PHP string trimming
Quick question (hopefully with a quick answer [img]images/smiles/icon_wink.gif[/img] )... Is there a way to trim strings in PHP to a certain length.

Reason being, I am calculating percents in my script and am getting really long number when I just want it rounded to say one decimal. Is there a function for this or must I write my own?

Thanks in advance for any help [img]images/smiles/icon_smile.gif[/img] .

float round ( float val [, int precision])

Returns the rounded value of val to specified precision (number of digits after the decimal point). precision can also be negative or zero (default).

round(3.5) = 4
round(3.4) = 3
round(4/3,2) = 1.33
round(5/3,1) = 1.7
