Buying .9 of an item...

[Eryqu]

Hello,

I have a small fantisy shop... where players can use their earned "credits" to buy fake items and such... My problem is that they can buy .[anything] of an item... they are charged .[number] of the cost but no item is assigned.

they can't buy below 1 though... soo if they tried to buy .2 it wouldnt work... if they tried to buy .9 it wouldnt work...

if they tried to buy 1.9 or 2.1 for example it would work... and if the item costed 1000 credits...
they would be charged 1900 and 2100 for the examples...

is there a way to only accept whole numbers...
what about checking to see if there is a . in the value submited?

Just need some help
Thanks

just round down whatever they enter... using the floor() function...

I think you want to allow any number greater than 1, correct? Just check to see if the variable is greater than one, and allow them to continue if it is. Then, round the number to the nearest tenth (or hundredth, depending on your preference).
