This is my test code:

import std.stdio;
import std.conv;
import std.string;

void main(string args[])
{
writeln(to!float(args[1])==to!float(args[2]));
}

When I enter 1E-7 and 1.0E-7 for arguments I get "false".

Why aren't these equal?  When parsing a text file that reads
these two values I need it to say they are equal.

Thanks.

Seems to be the same problem as discussed here: http://forum.dlang.org/thread/jsemibukuzkjssdbtkcf@forum.dlang.org
