double not recognised as as an alias of native float type from phpdoc blocks

[ghost]

I've got phpstan running checks on some code that uses the paypal php SDK & I'm getting what I think is an error that shouldn't be an error:

200 Parameter #1 $total of method PayPal\Api\Amount::setTotal() expects
string|PayPal\Api\double, float given.

(double) seems to be valid as a typecast, and is_double() is an alias of is_float(), so one would hope that this should be recognised as an alias of the system type float.

lib/PayPal/Api/Amount.php

    /**
     * Total amount charged from the payer to the payee. In case of a refund, this is the refunded amount to the original payer from the payee. 10 characters max with support for 2 decimal places.
     *
     * @param string|double $total
     * 
     * @return $this
     */
    public function setTotal($total)
    {

composer.lock snippet for the specific version:

        {
            "name": "paypal/rest-api-sdk-php",
            "version": "1.11.0",

            },

Hi, thanks for the report. I agree, I'll add it. If you want to, feel free to send a PR. It needs to be added here: https://github.com/phpstan/phpstan/blob/master/src/Type/TypehintHelper.php#L62 (and increase cache version in FileTypeMapper.php).

Work schedule is a bit crammed at the moment, I'm afraid.

Ok, I'll look into it. You can always vote with your money if you want the work done on your behalf 😊 I'd really appreciate your support.
