Hi, do someone know if, and how, we can make basic operation like sum, division and so on, simply with numbers?
Like a calculator, ex (4861/5000 -1)*299793

You mean in the CL? Simple, just prepend the expression with an '=', e.g.

cl> = (4861/5000 -1)*299793
-299793

Note you'll need to be explicit about using floating-point numbers (calculations are done internally as double precision. FWIW, you can use the same trick to evaluate sexigesimal values as well:

cl> = 12:34:56.7
12.582416666667

Remember to multiply RA by 15 8-)
