Remarks
The floating-point (Single) data type is useful for calculations that involve numbers too large to be represented as integers. Floating-point numbers are often expressed in exponential form (for example, 2.5e15), and can also be fractional or decimal numbers (in contrast to whole numbers). A number of this type can be precise (for rounding purposes) up to 7 digits.
Using the AsFloat methods, you can only convert a numeric value in string format to a Single value. Before you try to convert, you can check whether the string can be converted to this type by calling the IsFloat(String) method, which returns true if the string value can be converted.
