[amibroker] rounding

["holygrail168" <holygrail168@xxxxxxxxxxxx>]

Hi,

my buyprice functions are calculating values which go something like

7.395678

since these are in dollars, I want it to round to 3 significant figures 
so i get a value like 7.40

however, the AFL language only has round, ceil, floor which only 
performs rounding to the nearest integer.

so how do u guys do it then? it seems like a pretty basic function and 
i'm sure amibroker should have it but i've trawled thru the formula 
reference and can't find anything,

thanks
