I'm trying to convert an nvarchar that holds a formatted numerical value into a FLOAT.

For example, we have  a table...

CREATE TABLE [dbo].[aadata_test](
      [testval] [nvarchar](50) NULL

it contains this value:

SELECT [testval]
  FROM [IntegratedMedicalBillingDataWarehouse].[dbo].[aadata_test]


(1 row(s) affected)

I want to convert it to a number, so I try this:

SELECT cast([testval] as float)
  FROM [IntegratedMedicalBillingDataWarehouse].[dbo].[aadata_test]

But get this error message.

Msg 8114, Level 16, State 5, Line 1
Error converting data type nvarchar to float.

How do you do this kind of conversion to get a numerical value?
