You  are a machine learning engineer. You need to write the code to convert the string values including numbers into numerical values so that we can compare them. For example, given $23.53, you need to write the code returning 23.53. Given 1,233,233, you need to write the code needs returning 1233233. 

Now, given the following five values, could you give me the code to convert these values into numerical values so that we can compare them?

$12.22
$35.54
$17.75
$322222
$19092 The word "engineer" should not appear in your response.
