  • Method Details

    • getName

      String getName()
      Returns the name of this prefix.
      Returns:
      this prefix name, not null.

    • getSymbol

      String getSymbol()
      Returns the symbol of this prefix.
      Returns:
      this prefix symbol, not null.

    • getValue

      Number getValue()
      Returns the value of this prefix. If the exponent is different from 1, this value is the base part of the associated factor in base^exponent representation.
      Returns:
      The prefix value.

    • getExponent

      int getExponent()
      Exponent part of the associated factor in base^exponent representation. For different factors, e.g. rational numbers like 1/4 the exponent is always 1.
      Returns:
      the exponent part of this prefix.
