integer
X=X*Y
X=X/Y
X=X-Y
X=X+Y
Sets option bits
X=|X|
R0=X
X=R0

Notes and Key:
• FP – 32 bit floating point number (see text for format)
• DIGIT – A digit number. Zero returns +, -, or space if the number is
positive, negative, or zero. See reference for more details.
• ASCIIDIGIT – The ASCII representation of the requested digit
• STATUS – Floating point error flags
• OPTS – Options ( $80 turns on saturation; $40 enables rounding)
• R0, R1 – Temporary storage registers
