Enclose the string in the parentheses of that code. As well, inside those parentheses, add the parameter Locale.getDefault(), in the beginning. Then replace + with a comma. Put a placeholder for the first decimal that appears. DecimalFormat does not decide whether to return a Double or a Long based on the presence of a decimal separator in the source string. Doing so would prevent integers that overflow the mantissa of a double, such as -9,223,372,036,854,775,808.00 , from being parsed accurately Translates a double into a BigDecimal which is the exact decimal representation of the double's binary floating-point value.The scale of the returned BigDecimal is the smallest value such that (10 scale × val) is an integer. Notes: The results of this constructor can be somewhat unpredictable. One might assume that writing new BigDecimal(0.1) in Java creates a BigDecimal which is exactly.
