Function toExpression

src/compute-engine/free-functions.ts:58–71

Convert a LatexString, Expression, or ExpressionInput to a boxed Expression. * Strings are parsed as LaTeX. Parsing defaults to non-strict so the free * functions accept the looser AsciiMath/Typst-like syntax documented for them * — bare function names and multi-letter identifiers (`sqrt(5)`,

(
  input: LatexString | ExpressionInput,
  options?: FreeFunctionOptions
)

 *  `alpha`), and `**` for exponentiation — in addition to canonical LaTeX.
 *  Pass `{ strict: true }` to opt back into the strict LaTeX grammar. */
