Properties

Optionalalgebraic

algebraic?: boolean

Optionalcomplex

complex?: boolean

Optionalcomposite

composite?: boolean

constant

constant: boolean

If true the value of the symbol is constant. The value or domain of symbols with this attribute set to true cannot be changed.

If false, the symbol is a variable.

Default: false

Optionaldescription

description?: string | string[]

domain

domain: undefined | BoxedDomain

Optionaleven

even?: boolean

OptionalextendedComplex

extendedComplex?: boolean

OptionalextendedReal

extendedReal?: boolean

Optionalfinite

finite?: boolean

holdUntil

holdUntil:
    | "evaluate"
    | "N"
    | "simplify"
    | "never"

If the symbol has a value, it is held as indicated in the table below. A green checkmark indicate that the symbol is substituted.

| Operation | "never" | "simplify" | "evaluate" | "N" | | :--- | :----- | | canonical()| (X) | | | | | simplify() | (X) | (X) | | | | evaluate() | (X) | (X) | (X) | | | "N()" | (X) | (X) | (X) | (X) |

Some examples:

  • i has holdUntil: 'never'
  • GoldenRatio has holdUntil: 'simplify' (symbolic constant)
  • x has holdUntil: 'evaluate' (variables)
  • Pi has holdUntil: 'N' (special numeric constant)

Default: evaluate

Optionalimaginary

scope

scope: undefined | RuntimeScope

The scope this definition belongs to.

This field is usually undefined, but its value is set by getDefinition()

Optionalurl

url?: string

Optionalwikidata

wikidata?: string

Optionalzero

zero?: boolean

Accessors

value

  • get value(): undefined | BoxedExpression

  • Returns undefined | BoxedExpression

  • set value(val): void

  • Parameters

    Returns void

Methods

reset

  • reset(): any

  • When the environment changes, for example the numerical precision, call reset() so that any cached values can be recalculated.

    Returns any
