Struct ModeSingleFn 

pub struct ModeSingleFn;

Returns the most frequently occurring value in a data set.

MODE.SNGL returns a single mode value and reports #N/A if no value repeats.

Remarks

• Returns the first mode encountered after sorting when frequencies tie.
• Returns #N/A when every numeric value appears only once.
• Alias MODE is supported.

Examples

title: "Single mode from scalar arguments"
formula: "=MODE.SNGL(1,2,2,3)"
expected: 2

title: "Single mode from a range"
grid:
  A1: 4
  A2: 4
  A3: 6
  A4: 6
  A5: 6
formula: "=MODE.SNGL(A1:A5)"
expected: 6

Trait Implementations

impl Debug for ModeSingleFn

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Function for ModeSingleFn

[formualizer-docgen:schema:start] Name: MODE.SNGL Type: ModeSingleFn Min args: 1 Max args: variadic Variadic: true Signature: MODE.SNGL(arg1…: number@range) Arg schema: arg1{kinds=number,required=true,shape=range,by_ref=false,coercion=NumberLenientText,max=None,repeating=None,default=false} Caps: PURE, REDUCTION, NUMERIC_ONLY [formualizer-docgen:schema:end]

fn caps(&self) -> FnCaps

Capability flags for this function

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

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 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 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.
