MCO 305 Design Guide
Inform yourself about the type of assignment operation which is structured in accordance with the Bit/Byte
commands and about the priorities of the operators and the operations.
NB!:
All arithmetical operations are integer number operations.
Operators

+ plus
– minus
* times
% divided by
^ XOR
mod Modulo
rnd Division
abs Absolute
amount
Bit Operators
Symbol Meaning
& and
or
invert
<< left shift
>> right shift
. Bit
.b Byte
.w Word
.l Long
__ How to Program __
Syntax / Example
3 + 3 = 6
9 – 3 = 6
2 * 3 = 6
19 % 3 = 6
expr1 ^ expr2
127 ^ 255 = 128
expr1 mod expr2
250 mod 16 = 10
expr1 rnd expr2
250 rnd 16 = 16
Abs(expr)
abs (-5) = 5
Syntax / Example
7 & 6 = 6
2 | 4 = 6
(–7) = 6
3 << 1 = 6
12 >> 1 = 6
expr1.expr2
7.1 = 1
7.3 = 1
7.4 = 0
expr1.b expr2
0x027F.b1 = 127
0x027F.b2 = 2
expr1.w expr2
0x0010FFFF.w2 = 16
expr1.l expr2
