To read the integer, issue a READX. In
order to continue calculations with the
same number, you'll need to issue a
FLOAT command, or reload the X register.
It is often quicker to use a STO command
to save the X register, perform the INT
command, read the result, and then RCL
the original contents.
LOADX, LOADY
These commands take the next four bytes
you send and places them in the X or Y
register. The format is exponent first,
followed by the mantissa (most significant
bit first). You can also load integers or
IEEE format numbers for conversion using
this command.
LOG, LOG10
These commands find the natural or
common logarithm of X.
MUL
Multiplies X and Y leaving the result in X.
Y is unchanged. This command may take
approximately 120uS in the worst case.
OPT
Sets options. Send the option byte after this
command. Using $80 turns on saturation
(which represents over and underflows as
minimum and maximum values). Using
$40 enables rounding. If this option is not
