2*10e-11 --> 2*10e-10 ?

this

alert(2*10e-11);

alerts: 2*10e-10

?

1e2 = 1 * (10 ^ 2)

Basically, the e already includes the 10 in the times part.

In your example,

2*10e-11
= 2 * 10 * (10 ^ -11)
= 2 * (10 ^ (-11 + 1))
= 2 * (10 ^ -10)
= 2e-10

(which is what js alerts)

Yes...it's correct ;)

...This means that 10 is raised to the power of -11 which is 0.0000000001

The output above is exactly the same as:

alert(2*0.0000000001);
