7 – 118 HEIDENHAIN Technical Manual TNC 426, TNC 430
7.7.29 REMAINDER (MOD)
Syntax: MOD (MODULO)
Operands: B, W, D, K
Action:
The TNC extends the operand to the width of the accumulator (32 bits) and
then calculates the remainder resulting from the division of the content of the
word accumulator by the content of the operand. The remainder is stored in
the word accumulator where you can process it further. If the TNC cannot
execute the MOD command correctly, it sets marker M4202; otherwise it
resets it.
Example:
Divide the number saved in word W6 by the constant, then calculate the
REMAINDER and assign the result to double word D8.
Initial state:
Word W6 = 50 (dec)
Constant = 15 (dec)
Double word D8 = ?
To improve clarity, the contents of the accumulator and operand are shown in
decimal notation. The ten-digit accumulator results from the greatest possible
accumulator content (2 147 483 647).
