Calculating race results - dont get it...

kpowning

Ok I'm trying to calculate race results correctly for a customer. Basically there are 2 runs and so lets say the following

Last_name | run1 | run2 |

martinez 1 4
geoff 20 16

Ok so I need to be able to get the following totals for each person:

Martinez avg for both runs should put him at (3)
Geoff avg for both runs should put him at (19)

How can I calculate this in php?

I have tried the following but doesnt give me accurate results:

$test = round(($query['run1'] + $query['run2'])/2);
echo $test

Hi,

I presume the average for Martinez would actually be 2.5? (1+4 / 2) and then rounded up to 3?
Would Geoff not be average of 18? 20_16 / 2 does = 18. Where are you getting your averages from?

Martinez average for both runs would be 2.5 (5/2 = 2.5).

If you want to round up, use ceil(), to round down, use floor(). round() will round to the nearest whole number, or to the specified presicion.

What are you getting at the moment, and what would you like it to be instead?
