1e3 != 1000.

[MrGibus]

I'm a structural engineer, like many other people I expect that when I type 1e3 the result would be 1000. But what I actually get is 20.0855369232 which you're aware would be 1 * e * 3. The same can be said for exp. I think this is something that needs addressing because it will catch others out.

For precedence : On my graphics calculator if I hit 1 <EXP> 3 it means 1E3 == 1000. It's used extensively by scientists and engineers using the metric system.
