In the good old days when I did numerical processing on an IBM-709, I
considered two floating point numbers to be equal when the first N significant
bits of the mantissia were the same (N is of course problem dependent).  This
was easy to do in assembly language.  All that is needed is an unnormalized
subtract operator.

I too wish for a higher level way to specify the "fuzz" for equality.
