Expressions
In most cases, where a single integer or float value can be used as an operand, an expres-
sion can also be used. The assembler evaluates expressions in 32-bit signed arithmetic or
64-bit floating-point arithmetic. Logical expressions are bitwise operators.
The assembler detects overflow and division-by-zero errors. The following sections
describe the syntax of writing an expression:
•
