[LON-CAPA-users] display number with "E" scientific notation

[Moore, Nathan T]

Imagine I have a variable that's random

$length=&random(150,250,1);

Specific case, $length = 157;

I want this value to be printed for users with the "E" power of 10 notation, eg I want the user to see

1.57E2

The following code displays almost what I want, 1.57x10^2, but what I really want is 1.57E2 <num  format="%.02E">$length</num>

Thoughts on a workaround?
