Description |
+ |
 |
Addition. Add the value of the X register to the value of Y
register and return the answer in the X register. Contents of the Y register
are lost. |
- |
 |
Subtraction. Subtract the value of the X register from the
value of Y register and return the answer in the X register. Contents of the
Y register are lost. |
× |
 |
Multiplication. Multiply the value of the X register to the
value of Y register and return the answer in the X register. Contents of the
Y register are lost. |
÷ |
 |
Division. Divide the value of the X register into the value
of Y register and return the answer in the X register. Contents of the Y
register are lost. |
sqrt |
  |
Square root. Performs the square root of the value of the X
register and returns the answer to the X register. |
1/x |
  |
Inverse. Performs the inverse of the value of the X register
and returns the answer to the X register. |
ABS |
  |
Absolute value. Performs the absolute value of the value of
the X register and returns the answer to the X register. |
RMD |
  |
Remainder (modulus). Performs a modulus on the contents of
the X and Y registers. The answer is returned to the X register. The
contents of the Y register are lost. |
DBL× |
  |
Double precision multiplication. Multiply the value of the X
register to the value of the Y register and returns the answer split between
the X and Y registers. The X register contains the right-most bits (as
defined by word size), the Y register contains the left-most bits. |
DBL÷ |
  |
Double precision division. Divide the value split between
the Y and Z registers into the value of the X register and return the answer
in the X register. The Y register contains the left-most bits (as defined by
word size), the X register contains the right-most bits. |
DBLR |
  |
Double precision remainder (modulus). Performs the modulus
of the value split between the X and Z registers into the value of the X
register and return the answer in the X register. The Y register contains
the left-most bits (as defined by word size), the X register contains the
right-most bits. |
