Math Functions

Function Key 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.
