Alternative to integer to get number from variable including decimal but not a string

Question

I have a JSON object with order information in. Within this object is an amount for example "amount" : "82.95"

I have this within a variable called $amount and I am using it within an array by doing (int)$amount.

The problem with this is that it is removing the .95 which is required as it is an integer.

How can I get this value as a number and not a string not string but retain the .95?

Example:

$amount = 82.95;

echo (int)$amount;
// Result = 82

You do realise what casting to an integer does to a decimal, don't you? Why do you want to cast it to an integer anyway if you want to retain the decimals? — Mark Baker, Oct 12 '17 at 11:41

Sorry, I didn't write the question very well, I am looking for an alternative method than integer. I will update that now. — Ben H, Oct 12 '17 at 11:46

82.95 isn't an integer, so casting it as one isn't going to return 82.95. That type of number is a float:

$amount = '82.95';
echo (float) $amount;
// Result 82.95
