Using decimal numbers

A decimal number, sometimes called a floating-point number, is any number that includes a decimal point. The `floatPrecision` property controls the number of decimal places used to display these numbers. (However, Director always uses the complete number in calculations.) See the `floatPrecision` entry in Director Help or the Lingo Dictionary for information about setting the number of decimal places used for decimal numbers.

You can also use exponential notation with decimal numbers: for example, -`1.1234e-100` or `123.4e+9`.

You can convert an integer or string to a decimal number by using the `float()` function. For example, the statement `set theNumber = float(3)` stores the value `3.0` in the variable.
