Struct BitAndFn 

pub struct BitAndFn;

Returns the bitwise AND of two non-negative integers.

Combines matching bits from both inputs and keeps only bits set in both numbers.

Remarks

• Arguments are coerced to numbers and must be whole numbers in the range [0, 2^48).
• Returns #NUM! for negative values, fractional values, or values outside the supported range.
• Propagates input errors.

Examples

title: "Mask selected bits"
formula: "=BITAND(13,10)"
expected: 8

title: "Check least-significant bit"
formula: "=BITAND(7,1)"
expected: 1

faq:
  - q: "When does `BITAND` return `#NUM!`?"
    a: "Inputs must be whole numbers in `[0, 2^48)`; negatives, fractions, and out-of-range values return `#NUM!`."

Capability flags for this function

fn name(&self) -> &'static str

fn min_args(&self) -> usize

fn arg_schema(&self) -> &'static [ArgSchema]

fn eval<'a, 'b, 'c>( &self, args: &'c [ArgumentHandle<'a, 'b>], _ctx: &dyn FunctionContext<'b>, ) -> Result<CalcValue<'b>, ExcelError>

The unified evaluation path.

fn namespace(&self) -> &'static str

fn variadic(&self) -> bool

fn volatile(&self) -> bool

fn aliases(&self) -> &'static [&'static str]

Optional list of additional alias names (case-insensitive) that should resolve to this function. Default: empty slice. Implementors can override to expose legacy names. Returned slice must have ’static lifetime (typically a static array reference).

fn function_salt(&self) -> u64

fn eval_reference<'a, 'b, 'c>( &self, _args: &'c [ArgumentHandle<'a, 'b>], _ctx: &dyn FunctionContext<'b>, ) -> Option<Result<ReferenceType, ExcelError>>

Optional reference result path. Only called by the interpreter/engine when the callsite expects a reference (e.g., range combinators, by-ref argument positions, or spill sources).

fn dispatch<'a, 'b, 'c>( &self, args: &'c [ArgumentHandle<'a, 'b>], ctx: &dyn FunctionContext<'b>, ) -> Result<CalcValue<'b>, ExcelError>

Dispatch to the unified evaluation path with automatic argument validation.
