5 years ago parseExpression already converts the value property of number expressions to number, so I don't think we need to do that again when evaluating. Can you provide an example of a call to run that doesn't work as expected?

testing the run function it was concatenating instead of doing math.In the evaluate function where the expr.type is a value I had to add an if else statement to check if the value is a number then typecast it to a number.
if(/\d+/.test(expr.value)){ return Number(expr.value); }
