Convert hexadecimal value to real data type

Hi ,

I want to convert hexadecimal to numeric data type. Using directly Cast or Convert function is not working.

Please suggest an alternative how to retrieve the numeric value of binary data .

Thanks in advance

Srinivas,

Please show us what does not work for you. The following is

fine:

declare @.n numeric(10,2)

set @.n = 1.23

select cast(@.n as varbinary(20))

-- returns 0x0A0200017B000000

select cast(0x0A0200017B000000 as numeric(10,2))

If you are trying to convert binary representations of

[float] values to [float], you can use this code:

declare @.b binary(8)

set @.b = 0xC094D954FB549F95

declare @.s bit

declare @.e smallint

declare @.m float

set @.s = case when substring(@.b,1,1) >= 0x80 then 1 else 0 end

set @.e = (substring(@.b,1,2)&32752)/16-1022

set @.m = cast(substring(@.b,6,3) as int)/2097152e0/536870912e0

+ (substring(@.b,2,4)&268435455)/536870912e0+0.5e0

select case when @.s = 1 then -1e0 else 1e0 end * @.m * power(2e0,@.e)
