The highest number

It's known Scilab works as a calculator, displaying results of math operations.

I was trying to obtain the highest number that Scilab can work with, so it's what I found:

-->1.7976931348623158079999999999999999999999999999999999999e+308
 ans  =

    1.79D+308 

-->1.797693134862315808e+308
 ans  =

    Inf

It's a great number! And I think this number can attend all our needs for computations and operations.
