Unsigned Arithmetic Operators
Typically, you use binary unsigned arithmetic on operands with values in the range 0 through
65,535. For example, you can use unsigned arithmetic with pointers that contain standard
addresses.
Table 28 Unsigned Arithmetic Operators
ExampleOperand TypeOperationOperator
alpha '+' betaSTRING, INT, or
UNSIGNED(1-16)
Unsigned addition'+'
alpha '-' betaSTRING, INT, or
UNSIGNED(1-16)
Unsigned subtraction'-'
alpha '*' betaSTRING, INT, or
UNSIGNED(1-16)
Unsigned multiplication'*'
alpha '/' betaINT(32) or UNSIGNED (17-31)
dividend and STRING, INT, or
UNSIGNED(1-16) divisor
Unsigned division'/'
alpha '\' betaINT(32) or UNSIGNED (17-31)
dividend and STRING, INT, or
UNSIGNED(1-16) divisor
Unsigned remainder*'\'
* If the quotient exceeds 16 bits, an overflow condition occurs and the results will have unpredictable values. For
example, the operation 200000D '\' 2 causes an overflow because the quotient exceeds 16 bits.
In Table 29 (page 75), the order of the operand types in each combination is interchangeable
except in the last case.
