 Seems like the number type isn't returning 0 in the customizer


 Here's my control code in functions.php

 {{{
 $wp_customize->add_setting('apw_header_cta_padding_bottom', array(
 'default' => '20' ) );
         $wp_customize->add_control(
                 new Customize_Number_Control(
                         $wp_customize,
                         'header_cta_padding_bottom',
                         array(
                                 'label'      => 'Bottom Padding',
                                 'section'    => 'apw_header_cta',
                                 'settings'   =>
 'apw_header_cta_padding_bottom',
                                 'type'           => 'number',
                                 'priority'       => 30
                         )
                 )
         );
 }}}

 Then, in my header.php I have

 {{{
 <?php if(get_theme_mod( 'apw_header_cta_padding_bottom')) : ?>
 }}}

 Then, when I preview the site in the customizer and set that value to
 zero, this if statement returns false when the value should be zero.
