'1'.
Numbers greater than $80 return ASCII
characters to the right of the decimal point.
So using the same example, if you issue a
DIGIT $81, the return will be '1'. DIGIT
$82 will return '4'.
This command does not affect the X or Y
registers. It may take some time to execute
depending on the digit you request, and the
number in the X register.
This command performs a complex
algorithm which involves converting the
number to an integer and back to a float in
several places. Since integer to float
conversion is limited to 24 bits, this places
an upper limit on the size of the number
you can convert with DIGIT. Note that this
does not apply to using it as a replacement
for SGN. If you operate on a large number
(or a number with many significant digits)
and an intermediate result exceeds 24 bits,
you may get an incorrect answer, or the
PAK may fail to converge.
DIRA/B
These commands allow you to set the
directions of the two 8 bit I/O ports. On
power up, all pins are inputs. Setting a bit
to 1 in the DIR command causes the
