Does the expression 1+1 evaluate as 2 or does it evaluate to 2?

Is one (or both) of the above not proper English or misused in this context, or are they both okay?

Google Books (don't use vanilla Google) shows both work for digits for value:

"expression evaluates to 5" About 65 results

"expression evaluates as 5" 3 results

I'd prefer the "to" variant.

With literals for values (a, b, u), only t seems to work; I just wasn't able get any hits with "as." Others might know otherwise.


I would use only "to". "As" implies something like "in the guise or form of" and doesn't convey a the same sense of exactness as "to".
