This function has the same script as function decimalToOctal but with powers of 2.

function octalToDecimal (number) {
    array9.splice(0);
    array8.splice(0);
    for (i = 0; i <= length (number) - 1; i ++) {
        array8 [i] = Math.floor (number / Math.pow (10, length (number) - i - 1)) - Math.floor (number / Math.pow (10, length (number) - i)) * 10;
    }
    decimal1 = 0;
    for (j = 0; j < array8.length; j ++) {
        array9 [j] = Math.pow (8, array8.length - j - 1);
        decimal = array9 [j] * array8 [j];
        decimal1 += decimal;
    }
    return decimal1;
}

This function has the same script as function binaryToDecimal but with powers of 8.
