~ Operator

Purpose

a bitwise Not

Syntax

x% = ~ i

i:integer expression

Description

~ i inverts the bit pattern in i.

The one's complement operator, sometimes called the "bitwise complement" or "bitwise NOT" operator, produces the bitwise one's complement of its operand. The operand must be of integral type. This operator performs usual arithmetic conversions; the result has the type of the operand after conversion.

Example

Print Bin$(3, 32)    // Prints 00000000000000000000000000000011

Print Bin$(10, 32)   // Prints 00000000000000000000000000001010

Print Bin$(~3, 32)   // Prints 11111111111111111111111111111100

Print Bin$(~10, 32)  // Prints 11111111111111111111111111110101

Remarks

Not is synonymous with ~ and can be used instead. However, ~ has higher priority so

a% = ~b% + 4 = (Not b%) + 4

a% = ~(b% + 4) = Not b% + 4
