I am convinced there is a reason for needing udf instead of just using rand() directly. The request as is doesn’t make much sense. If a udf is required, maybe consider a CLR if option is available.

go
create function testRand(@rand1 float)
returns bigint
as
begin
– your logic to manipulate random value
return cast((@rand1*100000) as bigint)
end
go
select dbo.testRand(rand())
–cleanup
drop function dbo.testRand

You can also use a stored procedure with an output parameter:

Create procedure dbo.usp_Randomnumber @Somenumber float OUTPUT

as
Begin
Set @Somenumber = rand()
End
Go

Declare @Number float
Exec dbo.usp_Randomnumber @Number OUTPUT
Select @Number
