Struct IntFn 

pub struct IntFn;

Trait Implementations

impl Debug for IntFn

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

Formats the value using the given formatter.

impl Function for IntFn

Rounds a number down to the nearest integer.

INT uses floor semantics, so negative values move farther from zero.

Remarks

• Equivalent to mathematical floor (floor(x)).
• Coercion is lenient for numeric-like inputs; invalid values return an error.
• Input errors are propagated.

Examples

title: "Drop decimal digits from a positive number"
formula: "=INT(8.9)"
expected: 8

title: "Floor a negative number"
formula: "=INT(-8.9)"
expected: -9

faq:
  - q: "Why is INT(-8.9) equal to -9 instead of -8?"
    a: "INT uses floor semantics, so negative values round toward negative infinity."

fn caps(&self) -> FnCaps

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>], _: &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.
