Function evaluateModifierFormula

evaluateModifierFormula(
    formula: string,
    context?: object,
    actor?: any,
    options?: { floor?: boolean },
): number
Evaluate a modifier formula string to a number (floored by default). The formula can contain:
- Arithmetic operators: +, -, *, /
- Parentheses for grouping
- Functions: floor(), ceil(), round(), min(), max(), abs()
- Variable tokens: {numStacks}, {str}, {self.foo}, etc. (resolved via context/actor)
By default, the result is floored to an integer before returning. This behavior can be controlled via the options parameter.
Parameters
- formula: string
  The formula string (e.g., "0.5 * {numStacks}", "10 + floor({str}/2)")
- Optionalcontext: object = {}
  Context object with token values (e.g., { numStacks: 3 })
- Optionalactor: any = null
  Optional actor for attribute/vector token resolution
- Optionaloptions: { floor?: boolean } = {}
  Configuration options
  - Optionalfloor?: boolean
    
    Whether to floor the result to an integer
Returns number
The result, optionally floored

Throws
If the formula is invalid or evaluation fails
