# Change output to numerical values globally

I know how to make sage to output numerical results as described in http://ask.sagemath.org/question/8150...

However is there a magic line, a global variable or something like that to make sage output the numerical result directly in the following lines?

For example I don't want to type in

`n(sin(100))`

to get

`-0.506365641109`

or

`n(sqrt(pi()*2))`

to get

`2.50662827463100`

I just want to type `sin(100)`

or `sqrt(pi()*2)`

to get the numerical result.

Could you please give an example of a computation that you would see to appear numerically ?
