Set decimal quantity step at product level - php

Question

I am trying to combine the two responses from [https://stackoverflow.com/questions/62943477/set-quantity-minimum-maximum-and-step-at-product-level-in-woocommerce ] and Decimal quantity step for specific product categories in WooCommerce but I can't figure out how to edit the first lot of code so that it allows decimal quantity steps.
// Displaying quantity setting fields on admin product pages
add_action( 'woocommerce_product_options_pricing', 'wc_qty_add_product_field' );
function wc_qty_add_product_field() {
global $product_object;
$values = $product_object->get_meta('_qty_args');
woocommerce_wp_text_input( array(
'id' => 'qty_step',
'type' => 'number',
'label' => __( 'Quantity step', 'woocommerce-quantity-step' ),
'placeholder' => '',
'desc_tip' => 'true',
'description' => __( 'Optional. Set quantity step (a number greater than 0)', 'woocommerce' ),
'custom_attributes' => array( 'step' => 'any', 'min' => '1'),
'value' => isset($values['qty_step']) && $values['qty_step'] > 1 ? (int) $values['qty_step'] : 1,
) );
echo '</div>';
}
// Save quantity setting fields values
add_action( 'woocommerce_admin_process_product_object', 'wc_save_product_quantity_settings' );
function wc_save_product_quantity_settings( $product ) {
if ( isset($_POST['qty_args']) ) {
$values = $product->get_meta('_qty_args');
'qty_step' => isset($_POST['qty_step']) && $_POST['qty_step'] > 1 ? (int) wc_clean($_POST['qty_step']) : 1,
) );
} else {
$product->update_meta_data( '_qty_args', array() );
}
}
// The quantity settings in action on front end
add_filter( 'woocommerce_quantity_input_args', 'filter_wc_quantity_input_args', 99, 2 );
function filter_wc_quantity_input_args( $args, $product ) {
if ( $product->is_type('variation') ) {
$parent_product = wc_get_product( $product->get_parent_id() );
$values = $parent_product->get_meta( '_qty_args' );
} else {
$values = $product->get_meta( '_qty_args' );
}
if ( ! empty( $values ) ) {
// Step value
if ( isset( $values['qty_step'] ) && $values['qty_step'] > 1 ) {
$args['step'] = $values['qty_step'];
}
}
return $args;
}
// Ajax add to cart, set "min quantity" as quantity on shop and archives pages
add_filter( 'woocommerce_loop_add_to_cart_args', 'filter_loop_add_to_cart_quantity_arg', 10, 2 );
function filter_loop_add_to_cart_quantity_arg( $args, $product ) {
$values = $product->get_meta( '_qty_args' );
if ( ! empty( $values ) ) {
// Min value
if ( isset( $values['qty_min'] ) && $values['qty_min'] > 1 ) {
$args['quantity'] = $values['qty_min'];
}
}
return $args;
}
I've tried editing the values to a decimal unit but it's not stepping up by that value and it's not saving the value.
