Function: formatNumber()

formatNumber(value, precision?): string

Defined in: charts/src/core/options.ts:38

Formats a numeric value as a localized string, capping the precision at precision decimal places (default DEFAULT_NUMBER_PRECISION). Integers render without decimals; fractional values are rounded to at most precision places with trailing zeros stripped. Non-numeric values fall back to String(value). This is the shared entry point every chart uses so labels, axes, tooltips, and tick marks share one consistent precision cap.

Parameters

Parameter	Type	Default value
value	unknown	undefined
precision	number	DEFAULT_NUMBER_PRECISION

Returns

string
