Member Function Documentation

char * Prefix::abbr ( ) [inline]

Return the abbreviation of a prefix

bool Prefix::avoid ( ) const [inline]

Is this prefix to be avoided?

void Prefix::avoid ( const bool & state ) [inline]

Denote this prefix as one to be avoided for common use.

int Prefix::exp ( ) [inline]

Return the exponent associated with the prefix. If this prefix is present in front of a unit, then the number must be multiplied by 10^exp() to remove the prefix. For example, since the quantity "101 kPa" is preceded by "k", the abbreviation for "kilo", then we must multiply by 10^3 (=1000) in order to remove the "k". So "101 kPa = 101000 Pa".

char * Prefix::name ( ) [inline]

Return the name of the prefix (i.e., "kilo" or "mega"). No dash should appear at the end of a name. The name should be entirely lowercase letters (no capitalization).

Prefix * Prefix::next ( ) [inline]

Return the next prefix in the list of all prefixes.
