Comparing variables of different types

[40inD]

Can I compare float and int?
for ex. if (float<int)

[Ttelmah]

Yes.
However the results will have the normal 'float' inaccuracies.
Basically, the 'int', will automatically be converted to a float, and then the comparison will be performed. This means the comparison will involve a lot more work.
If you just want to check if the float is 'past' an integer boundary, then consider converting the float to an integer, and performing the comparison on this. So:

if ((int16)float<int16)

This gives slightly faster performance (I have assumed your 'int', is an int16, since otherwise the range becomes very small...).
