Detailed Description

A decimal (metric) prefix.

A metric or decimal prefix has an integer exponent which with a base of ten constitutes the value of the prefix (value=10^exponent).

Constructor & Destructor Documentation

DecimalPrefix()

DecimalPrefix::DecimalPrefix	(	int	exp10,
		std::string	long_name,
		std::string	short_name = "",
		std::string	unicode_name = ""
	)

Create a decimal prefix.

Parameters

exp10	Exponent for the value.
long_name	Long name.
short_name	Short name.
unicode_name	Unicode name.

Member Function Documentation

exponent() [1/2]

Number DecimalPrefix::exponent

(

const Number &

nexp

)

const
