wc_format_decimal

Format decimal numbers ready for DB storage.

Description

(string) wc_format_decimal( (number) $number, (constant) $dp = false, (bool) $trim_zeros = false );

Sanitize, remove locale formatting, and optionally round + trim off zeros.

Returns (string)

Parameters (3)

0. $number (number): Expects either a float or a string with a decimal separator only (no thousands)
1. $dp — Optional. (constant) => false: Number of decimal points to use, blank to use woocommerce_price_num_decimals, or false to avoid all rounding.
2. $trim_zeros — Optional. (bool) => false: From end of string

if ( !function_exists( 'wc_format_decimal' ) ) { 
    require_once ABSPATH . PLUGINDIR . 'woocommerce/includes/wc-formatting-functions.php'; 
} 
  
// Expects either a float or a string with a decimal separator only (no thousands) 
$number = null; 
  
// number of decimal points to use, blank to use woocommerce_price_num_decimals, or false to avoid all rounding. 
$dp = false; 
  
// from end of string 
$trim_zeros = false; 
  
// NOTICE! Understand what this does before running. 
$result = wc_format_decimal($number, $dp, $trim_zeros);
