Method Summary

Modifier and Type	Method	Description
int	getExponent()	Exponent part of the associated factor in base^exponent representation.
String	getName()	Returns the name of this prefix.
String	getSymbol()	Returns the symbol of this prefix.
Number	getValue()	Returns the value of this prefix.

Method Detail

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.
