Floating point is really stupid for most computations. Can't store floating point numbers when dealing with money (have to store the number of cents or something equally stupid so you don't tell Paypal to sell something for $12.999999999999996 because they won't accept that price)

Can't store floating point numbers when you really need a ratio because it won't even work after you round it unless you reconcile different settings for precision. Decimal won't help here either.

So outside of niche scientific uses or something like graphics where you need performance, what do you really need floating point numbers for? I haven't had a need for floating point numbers outside of some mathematical formulae.
