# I need help with Sagetex/Sage (normal form&data file useage)

Greetings!

I have two questions.

The easier is, how can i "ask" Sagemath to numerically calculate, and use normal form. For example i would like to see sqrt{2}/10 as 1.41 * 10^{-1}. It would be useful to always get the same precision. Like 2/10 as 2.00 * 10^{-1}

The harder question is, i want to make several calculations with the same data (about 10-20 lines, every line with 2-4 records). It is possible to copy and paste it every time, but i rather do it an easier way. Is it possible?

I think if you reverse your order of questions, you will get a better answer. For example, if you tell us what you're trying to calculate, we can help. Then if you want to display the results in a certain format after the calculation, we can help with that too. =)

Hello! (d/2)*sin(((360-f(344,04,32))/(180))*pi)).n() would be the example calculation. I'd like to get 4.47 e-7. Problem is, the other calculation is{(360-f(351,31,23)+f(8,29,18))/2.n() and it should give 8.48. Ps. f calculates x°y'z'' to simple degrees
