Maths

Every so often, I realise just how bad I can be at Maths. Today (and, in fairness, last night) were perfect examples of that.

I’ve been writing the PHP to do a bundle of reports, and one of them involved figuring out the return-on-investment (ROI) for a given contract. It’s a simple percentage, yet could I get it right first time? Could I knickers. OK, some of the problems were with getting the information out of the database in the first place as well, but all the same, it led to me bashing my head into the desk for a good hour just on getting the sums right and then the percentages.

And the real bummer is that I’m still not convinced I’ve got it right…

Updated : Ah, got it sussed now, and all seems to be working fine. Funny how the simple things are always the hardest to fix, isn’t it?
