### 3.6.3. Numeric expressions

Numeric expressions consist of combinations of numeric constants,
numeric variables, ordinary numeric literals, binary operators,
and parentheses. See:

Numeric expressions can contain register-relative or program-relative
expressions if the overall expression evaluates to a value that
does not include a register or the PC.

Numeric expressions evaluate to 32-bit integers. You can interpret
them as unsigned numbers in the range 0 to 2^{32}-1,
or signed numbers in the range -2^{31} to
2^{31}-1. However, the assembler makes no
distinction between -`n`

and 2^{32}-`n`

.
Relational operators such as >= use the unsigned interpretation.
This means that 0 > -1 is `{FALSE}`

.

a SETA 256*256 ; 256*256 is a numeric expression
MOV r1,#(a*22) ; (a*22) is a numeric expression
