Format
NOT(<expression>)
Parameter
Return value
Returns an integer "not" value.
Description
Gets the "not" result of the 32-digit binary value specified in the <expression> parameter by inverting each bit.
If a double precision real number expression is specified in the <expression> parameter, the value is treated
as a value with digits to the right of the decimal point rounded off.
If an incorrect data type is specified for a parameter, a "Type mismatch" error will occur.
If a value outside the range -2147483648 to 2147483647 is specified as an integer parameter, an "Overflow"
error will occur.
If a value is assigned to the return value variable or the variable is not used in an expression, a "Syntax error"
error will occur.
If the format is written incorrectly, such as writing the macro function name incorrectly, omitting a comma, or
omitting a half-width space, a "Syntax error" error will occur.
Usage Cautions
• None.
