Function formula

formula(
toEval: string,
parameters?: PFormulaParameters,
): { formula: string; result: number }
Evaluates a mathematical expression given as a string. Supports the use of parameter placeholders (prefixed with $), which are replaced with values from the parameters object before evaluation.

You can use numbers, placeholders, and the following functions within the expression:
- avg(p1, p2, ...): Returns the average of the given numbers.
- pow(p1, p2): Returns the result of raising p1 to the power of p2.
- pi(): Returns the value of PI.
- e(): Returns the value of Euler's number (e).
Parameters
- toEval: string
  The formula string to evaluate. Placeholders must be in the form of $paramName.
- Optionalparameters: PFormulaParameters
  An optional object containing values to replace placeholders in the formula.
Returns { formula: string; result: number }
The results of the evaluated formula.
Example
```
console.log(PUtilsMath.formula('1 + 2')) // 3
console.log(PUtilsMath.formula('5 * 6')) // 30
console.log(PUtilsMath.formula('$one + 10', { one: 3 })) // 13
console.log(PUtilsMath.formula('$one + $two', { one: 5, two: '$one' })) // 10
console.log(PUtilsMath.formula('pi() + 1')) // 4.1416...
```
