SiUnitField.js (1521B)

      1 /**
      2  * This class represents a field which can handle a number (value) bound to a specific SI prefix.
      3  *
      4  * Internally, we use an object as value. Example:
      5  *
      6  * {
      7  *     value: 10 		// The base value, in our case 10
      8  *     symbol: "n" 		// The symbol for display
      9  *     power: -9    	// The power
     10  *     siprefix_id: 5	// The ID of the siprefix record  
     11  * }
     12  *
