cast or convert a float to nvarchar?

Question

I need to select from one column of datatype float and insert it in another column as nvarchar.

I tried to cast it: cast([Column_Name] as nvarchar(50))

Answer 1

Float won't convert into NVARCHAR directly, first we need to convert float into money datatype and then convert into NVARCHAR, see the examples below.

Example1

SELECT CAST(CAST(1234567890.1234  AS FLOAT) AS NVARCHAR(100))

output

1.23457e+009

Example2

SELECT CAST(CAST(CAST(1234567890.1234  AS FLOAT) AS MONEY) AS NVARCHAR(100))

output

1234567890.12

In Example2 value is converted into float to NVARCHAR
