Comparison and logic operations

Function
Comparison operations can be used, for example, to formulate a jump condition. Complex
expressions can also be compared.
The comparison operations are applicable to variables of type

Logic operators are used to link truth values.
The logical operations can only be applied to type

For the logic (Boolean) operations, the following applies to the
types:
● 0 corresponds to: FALSE
● Not equal to 0 means: TRUE
Bit-by-bit logic operators
Logic operations can also be applied to single bits of types
