Floating point data types are 32 bit numbers in IEEE-754 form. If you want a decimal point in your number, then it is a float.
The Range is 1.175494351E-38 to 3.402823466E+38
They can be specified in scientific notation like 2.6E-5.
If a function requires a float as a parameter, and the number is an integer (e.g. 5), be sure to add a .0 so it is created as a float (e.g. 5.0)
If you are dividing 2 constants, be sure to define them as floats or your result may get rounded. Better yet, do the math on your calculator and save the server some cycles.
