pub struct RoundUpFn;

Trait Implementations

impl Debug for RoundUpFn

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

Formats the value using the given formatter.

impl Function for RoundUpFn

Rounds a number away from zero to a specified number of digits.

Remarks

• Positive num_digits affects decimals; negative values affect digits left of the decimal.
• Any discarded non-zero part increases the magnitude of the result.
• Input errors are propagated.

Examples

title: "Round up decimals away from zero"
formula: "=ROUNDUP(3.14159,3)"
expected: 3.142

title: "Round up a negative value at the hundreds place"
formula: "=ROUNDUP(-987.65,-2)"
expected: -1000

faq:
  - q: "What does ROUNDUP do when discarded digits are already zero?"
    a: "It leaves the value unchanged because no non-zero discarded part remains."

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.
