Usage

From source file:Main.java

public static double parseDouble(String s) throws NumberFormatException {
    boolean negative = (s.charAt(0) == '-'); // Check if negative symbol.
    double result = 0.0D; // Starting value
    int index = s.indexOf('.');

    if (index > -1) {
        // Means the decimal place exists, add values to right of it
        int divisor = 1;
        for (int i = index + 1; i < s.length(); i++) {
            divisor *= 10;/*from ww w .j  a  v  a 2s.co  m*/
            int curVal = (s.charAt(i) - 48); // Convert char to int
            if (curVal > 9 | curVal < 0)
                throw new NumberFormatException();
            result += ((double) curVal / divisor);
        }
    } else {
        index = s.length(); // If number string had no decimal
    }

    // Now add number characters to left of decimal
    int multiplier = 1;
    // TODO: Note: Sven removed a test here for no decimal place. Unsure if needed.
    // Check old version of SVN to see old line.
    int finish = negative ? 1 : 0; // Determine finishing position

    for (int i = index - 1; i >= finish; i--) {
        int curVal = (s.charAt(i) - 48); // Convert char to int
        if (curVal > 9 | curVal < 0)
            throw new NumberFormatException();
        result += (curVal * multiplier);
        multiplier *= 10;
    }
