Number punctuation in price tags

Dear all,

In my site, all my price tag are displayed in format 1,000,000. I would like to display in format 10,00,000 (from last three commas ,followed by 2 commas)

I see in functions.php ,thousands_sep fucntion is doing to this operation. How can I make to display integers as I desire .

function number_format_i18n( $number, $decimals = 0 ) {
 173      global $wp_locale;
 174      $formatted = number_format( $number, absint( $decimals ), $wp_locale->number_format['decimal_point'], $wp_locale->number_format['thousands_sep'] );
 175
 176      /**
 177       * Filter the number formatted based on the locale.
 178       *
 179       * @since  2.8.0
 180       *
 181       * @param string $formatted Converted number in string format.
 182       */
 183      return apply_filters( 'number_format_i18n', $formatted );
 184  }
