checking if a variable is a float?

[Adamthenewbie]

How do I just check if a variable is a floating point number.

If its not a floating point number I want to throw an error.

What I have been trying is like this.. I am guessing there is a better way. plus this doesnt work anyway with letters and stuff...

if (($updatedMileage >= 0) && ($updatedMileage <= 9999)) {
IS A FLOATING POINT NUMBER
}
else {
ISNT A FLOATING POINT NUMBER
}

sorry,

I posted in the newbie forum first and noticed there was many more people viewing the General Forum so I though I would get a quicker reply
