[Mono-devel-list] NumberFormatter problem with mono-api-info.exe

[Sebastien Pouliot]

Hello,

The mono-api-info tool seems to have a problem with the new
NumberFormatter class.

This seems to affect both the NET_1_1 profile
http://mono.ximian.com:8008/amd64-head-mono/events/863/log
and the NET_2_0 profile
http://mono.ximian.com:8008/intel-head-mono/events/971/log


The two errors seems identical but the first is most useful as it
includes the line numbers:

Unhandled Exception: System.ArgumentException: An invalid argument was
specified.

The error probably comes from:

	if (float.IsNaN (value) || float.IsInfinity (value))
		throw new ArgumentException ();

Maybe there should be a string representation for NaN or Infinity ?
