tgl=> select cash_mul_flt8('$123.77', '1');
cash_mul_flt8
-------------
$123.77
(1 row)

tgl=> select cash_mul_flt8('$1', '123.77');
cash_mul_flt8
-------------
$123.76
(1 row)

That's annoying; it's non-symmetric too. The money type is stored as an
integer, and the float type is an IEEE double; looks like we have an LSB
rounding problem. Not sure what to do about it other than remove the
function, which isn't desirable I'm sure...
