I use StrToFloat, if this fails, it raises an exception (Which is fine of

But what I am trying to achieve here is to ensure the data integrity, does the data meet the float bounds?????

StrToFloat will almost certainly do that too. Give it a try with a really big float, something like 10E1000.

The StrToFloat function ultimately calls System.Double.TryParse(String,NumberStyles,IFormatProvider,out Double) to do the conversion.

Assigning a Double to a Single will throw an ArithmeticException if the result is not finite.
