Detailed Description

A binary prefix.

A Binary prefix has an integer exponent which with a base of two constitutes the value of the prefix (value=2^exponent).

Constructor & Destructor Documentation

BinaryPrefix::BinaryPrefix	(	int	exp2,
		string	long_name,
		string	short_name = "",
		string	unicode_name = ""
	)

Create a binary prefix.

Parameters

exp2	Exponent for the value.
long_name	Long name.
short_name	Short name.
unicode_name	Unicode name.

Member Function Documentation

int BinaryPrefix::exponent

(

int

iexp = 1

)

const

Returns the exponent.

Parameters

iexp	Exponent of the unit.

Returns

The exponent of the prefix.

Number BinaryPrefix::exponent

(

const Number &

nexp

)

const

Returns the exponent.

Parameters

nexp	Exponent of the unit.

Returns

The exponent of the prefix.

void BinaryPrefix::setExponent

(

int

iexp

)

Parameters

nexp	The power of the prefixed unit.

Returns

The value of the prefix.

Implements Prefix.

Number BinaryPrefix::value ( int  iexp ) const

virtual

Returns the value of the prefix.

Parameters

iexp	The power of the prefixed unit.

Returns

The value of the prefix.

Implements Prefix.

Number BinaryPrefix::value ( ) const

virtual

Returns the value of the prefix.

Returns

The value of the prefix.

Implements Prefix.
