please explain syntax

[webguync]

echo number_format(($avg/16)*100, 2);

 

in the above syntax, is the , 2 part determining that the resulting number will have 2 decimal places? Also, is order of the algorithm doing the division first and then the multiplication x 100?

 

 

thx

If you ever don't know what a function parameter does, just PLEASE read the manual.  It explains everything.

And yes, it's division then multiplication, just look at the parentheses.

[akitchin]

even if the parentheses weren't there, PHP follows order of operations as with any other mathematical incarnation (multiplication and division are performed on the same iteration, from left to right in the order they're found).  order of operations is a good thing to know whether you're programming or not, FYI.
