Struct Hex2OctFn 

pub struct Hex2OctFn;

Converts a hexadecimal text value to octal text.

Supports optional left-padding through the places argument.

Remarks

• Input must be hexadecimal text up to 10 characters and may be signed two’s-complement.
• Converted values must fit the octal range [-2^29, 2^29 - 1], or #NUM! is returned.
• places must be at least the output width and at most 10, or #NUM! is returned.

Examples

title: "Convert hex to octal"
formula: "=HEX2OCT(\"1F\")"
expected: "37"

title: "Convert signed hex"
formula: "=HEX2OCT(\"FFFFFFFFFF\")"
expected: "7777777777"

  - q: "What causes `HEX2OCT` to return `#NUM!`?"
    a: "The decoded value must fit octal output range `[-2^29, 2^29 - 1]`, and optional `places` must be valid."

Capability flags for this function

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

fn min_args(&self) -> usize

fn variadic(&self) -> bool

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 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.
