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,
std::string  long_name,
std::string  short_name = "",
std::string  unicode_name = "" 
)

Create a binary prefix.

Parameters
exp2Exponent for the value.
long_nameLong name.
short_nameShort name.
unicode_nameUnicode name.

Member Function Documentation

int BinaryPrefix::exponent ( int  iexp = 1) const

Returns the exponent.

Parameters
iexpExponent of the unit.
Returns
The exponent of the prefix.
Number BinaryPrefix::exponent ( const Number nexp) const

Returns the exponent.

Parameters
nexpExponent of the unit.
Returns
The exponent of the prefix.
void BinaryPrefix::setExponent ( int  iexp)

Sets the exponent of the prefix.

Parameters
iexpNew exponent for the prefix.
int BinaryPrefix::type ( ) const
virtual

Returns type, subclass, of the prefix. This can be PREFIX_DECIMAL for prefixes of the class DecimalPrefix, PREFIX_BINARY for BinaryPrefix, or PREFIX_NUMBER for NumberPrefix.

Returns
The type of the prefix.

Implements Prefix.

Number BinaryPrefix::value ( const Number nexp) const
virtual

Returns the value of the prefix.

Parameters
nexpThe 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
iexpThe 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.
