    Properties

    calculator?: Calculator

    Custom operator implementation. Defaults to StandardCalculator. Override to change how operators behave - for example to support arbitrary-precision arithmetic via a library such as Decimal.js.

    functions?: Map<string, ExpressionFunction>

    Custom functions available by name within expressions.

    lazyParams?: Map<string, LazyParameter>

    Named parameters whose values are computed on demand the first time they are referenced.

    params?: Map<string, Parameter>

    Named parameter values available during expression evaluation. Keys are parameter names used in the expression - without surrounding brackets.

    new Map([['x', 10], ['label', 'hello']])
    stopOnFirstError?: boolean

    Stop parsing on the first recoverable error when expression is provided as a string.

    true
