Implementation

	} else if( charAt( str, i ) == '-' ){
		swi = true;
		i++;
	}
	int chr;
	int num = (radix > 10) ? 10 : radix;
	while( i < str.length ){
		chr = charCodeAt( str, i );
		val *= radix;
		if( (chr >= charCode0) && (chr < charCode0 + num) ){
			val += chr - charCode0;
			i++;
		} else if( (chr >= charCodeLA) && (chr < charCodeLA + (radix - 10)) ){
			val += 10 + (chr - charCodeLA);
			i++;
		} else if( (chr >= charCodeUA) && (chr < charCodeUA + (radix - 10)) ){
