You could use python's string formatting to print numbers in scientific notation:

```
sage: n = 215.685
sage: print "my number is %e"%n
my number is 2.156850e+02
sage: print "my number is %E"%n
my number is 2.156850E+02
```

Is that the kind of thing you're looking for?

No. I want something like that: sage: x=1.2345678 -> sage: x -> 1.2345678 sage: x = 0.00003 -> sage: x -> 3E-05. Sage print a number x in scientific notation if x>=10^7 or 0 < x <= 10^-7.

Maybe the ticket http://trac.sagemath.org/sage_trac/ticket/7682 would resolve the issue?

Get Sage to display the 2nd x value, when function is set to 0?

Converting string into number does not work properly

What are the differences between RealDoubleField() and RealField(53) ?

Why is 3e1 not equivalent to 30?

check if the result is a real number
