Template:Rooteval

This template has worked but now gives an error:

• "{{rooteval|9}}" gives "(Expression error: Unexpected < operator / 10000000000 / 10000000000 / 10000000000)" [1]

even though it still works with substitution:

• (Expression error: Unexpected < operator / 10000000000 / 10000000000 / 10000000000)

[edit] Usage

• "{{rooteval|.0000000000001}}" gives "(Expression error: Unexpected < operator / 10000000000 / 10000000000 / 10000000000)" [2]

on which #expr can be applied directly, giving Expression error: Unexpected < operator, but which can also be used in a further computation, unlike that final result.
