Lua multiplication problem

[Tom Reahard <tom@...>]

I am experiencing some strange behavior with numbers where the results 
of a multiplication should equal a given number but Lua does not 
recognize the equality.

Here are some examples:

if ( 20425 * .053 ) == 1082.525 then print ("equal") else print ("not 
equal") end
if rawequal( 20425 * .053, 1082.525 ) then print ("equal") else print 
("not equal")end

Both result in "not equal".  Lua interprets the multiplication as less 
than the correct number.

if ( 20425 * .053 ) < 1082.525 then print ("less than") else print ("not 
less than") end
less than

I am using Lua 5.02 on Windows from the LuaBinaries (Release 2).  I 
quickly downloaded and tested Lua 4.0 and it has the same issue.

Thanks for any help on this.
