How to execute mathematical expression stored in a varchar variable

Question

I have a variable in my database function:

@LocalVariable = \'2*3*100\'

I want to get the result by executing the expression in another var

Answer 1

I got a better solution, I though of sharing with you all

DECLARE @x xml
DECLARE @v FLOAT
SET @x = ''
SET @v = @x.value('(1 + 4) div 3', 'FLOAT')
SELECT @v

This will work in function too.
