  • Method Details

    • trimInsignificantZeros

      public static java.lang.String trimInsignificantZeros​(java.lang.String floatingPointNumber)
      Removes trailing zeros after the decimal dot and also the dot itself if there are no non-zero digits after it. Use trimInsignificantZeros(String, DecimalFormatSymbols) instead of this method if locale specific behavior is desired.
      Parameters:
      floatingPointNumber - the string representing a floating point number
      Returns:
      the original number with trailing zeros removed

    • trimInsignificantZeros

      public static java.lang.String trimInsignificantZeros​(java.lang.String floatingPointNumber, java.text.DecimalFormatSymbols symbols)
      Removes trailing zeros after the decimal separator and also the decimal separator itself if there are no non-zero digits after it.
      Parameters:
      floatingPointNumber - the string representing a floating point number
      symbols - the decimal format symbols
      Returns:
      the original number with trailing zeros removed

    • trimInsignificantZeros

      public static java.lang.String trimInsignificantZeros​(java.lang.String floatingPointNumber, char decimalSeparator, java.lang.String exponentialSeparator)
      Removes trailing zeros after the decimal separator and also the decimal separator itself if there are no non-zero digits after it.
      Parameters:
      floatingPointNumber - the string representing a floating point number
      decimalSeparator - the decimal separator
      exponentialSeparator - the string used to separate the mantissa from the exponent
      Returns:
      the original number with trailing zeros removed
