Math - Binary (MATHBIN) (IB-501)
Math - Binary Format lets you enter complex
mathematical expressions like you would in Visual
Basic, Excel, or C++ to do complex calculations,
nesting parentheses up to 4 levels deep. In addition
to + - * /, you can do Modulo (% aka Remainder),
Shift Right (>>) and Shift Left (<<), Bit-wise And
(&) Or (|) Xor (^), and some binary functions -
Convert to BCD (BCD), Convert to Binary (BIN),
Decode Bits (DECO), Encode Bits (ENCO), Invert
Bits (INV), HEX to Seven Segment Display (SEG),
and Sum Bits (SUM).
Example: ((V2000 + V2001) / (V2003 - K10)) * SUM(V3000 & K001F)
Every V-memory reference MUST be to a single-word binary formatted value. Intermediate
results can go up to 32-bit values, but as long as the final result fits in a 16-bit binary word,
the calculation is valid. Typical example of this is scaling using multiply then divide, (V2000
* K1000) / K4095. The multiply term most likely will exceed 65535 but fits within 32 bits.
The divide operation will divide 4095 into the 32-bit accumulator, yielding a result that will
always fit in 16 bits.
You can reference BCD V-memory values by using the BIN conversion function on a
V-memory location but NOT an expression. That is, BIN(V2000) is okay and will convert
V2000 from BCD to Binary, but BIN(V2000 + V3000) will add V2000 as Binary, to V3000
as Binary, then interpret the result as BCD and convert it to Binary - NOT GOOD.
Also, the final result is a 16-bit binary number and so you could do BCD around the entire
operation to store the result as BCD.
MATHBIN Parameters
• Result (WORD): specifies the location where the binary result of the mathematical expression will
be placed (result must fit into 16-bit single V-memory location).
• Expression: specifies the mathematical expression to be executed and the result is stored in specified
Result (WORD). Each V-memory location used in the expression must be in binary format.
