Better avoid decimal fractions!

They can't always be transformed loss-free to binary fractions (see Re: eq vs ==)

But this works:

  DB<107> $x=95*806 /100;
 => "765.7"

  DB<108> $y=13*589 /10;
 => "765.7"

  DB<109>  $x <=> $y
 => 0

So just calculate with integers and shift the decimal point afterwards!

The deeper reason for this mess is that Humans have too many fingers ;-)
