Description George Staikos 2005-10-04 11:15:15 PDT 
toExponential() doesn't handle: 
- no arguments 
- large arguments 
- invalid arguments 
 
FireFox passes these: 
Number(123.456).toExponential() == 1.23456e+2 
Number(123.456).toExponential(21) == 1.234560000000000030695e+2 
Number(123.456).toExponential("foo") == 1e+2 
 
I have a patch for the first case but not the rest.
Comment 1 Alexey Proskuryakov 2006-01-13 13:27:04 PST 
Confirmed with ToT; the first case now works as described.
Comment 2 Sam Weinig 2007-02-23 19:25:22 PST 
For the large arguments part, Firefox supports sizes up to 100, and reports a "precision <num> out of range" error for anything greater.
Comment 3 Mark Rowe (bdash) 2007-11-01 06:52:49 PDT 
Another case reported on IRC:
1..toExponential(10) == 1.0000000000e+0

WebKit currently reports 1e+0.

The patches attached to bug 16640 make us pass these tests.  I'm going to dup
this to bug 16640 unless there are objections.
