I tried to add settings in the Customizer that are numbers with decimal point (period) and sanitize will fail or NULL my value, any function in WordPress to sanitize for decimal numbers and not only basic integers

If you are using absint than you must stop using that because it will reject any number that is negative or decimal range

@OP you need to write your own sanitize function for float numbers then:

[Roy]

function sanitize_float( $input ) {
    return filter_var($input, FILTER_SANITIZE_NUMBER_FLOAT, FILTER_FLAG_ALLOW_FRACTION);
}

[Denise]

this guy also failed from cause of absint

https://wordpress.stackexchange.com/questions/311152/customizer-how-to-sanitize-a-decimal-number-range

seems PHP needs to have more options for sanitize functions.

even WP is limited options.

I learned something new today!
