Mul.v
The mul.v command multiplies two variables and stores the result in the first.
Syntax
mul.v(var vA, var vB);
vA = vA * vB;
vA *= vB;
Remarks
Because variables are 8 bit unsigned numbers, if the result of the multiplication exceeds 255, the result 'wraps around'. For example, if v50 currently equals 200, and v51 equals 3, the statement:
mul.v(v50, v51);
will result in a value for v50 of 88 (200 * 3 = 600; 600 - 512 = 88). This can be represented mathematically as vA = (vA * vB) mod 256.
Note that this command uses the 'dot' notation (i.e. mul.v vs. mulv) unlike the original set of mathematical commands.
Possible Errors
None.
Example
<syntaxhighlight lang="agi"> v50 = 40; v51 = 5; mul.v(v50, v51); [ v50 now equals 200 v50 = v50 * v51; [ v50 now equals 232 (1000 - 256 * 3) v50 *= v51; [ v50 now equals 136 (1160 - 256 * 4) </syntaxhighlight>
