## 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 | ( | int | exp10,
|  | string | long_name,
|  | string | short_name = `""`,
|  | 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

int DecimalPrefix::exponent | ( | int | iexp = `1` | ) | const

Returns the exponent.

Parameters

  iexp | Exponent of the unit.

Returns
  The exponent of the prefix.

Number DecimalPrefix::exponent | ( | const Number & | nexp | ) | const

Returns the exponent.

Parameters

  nexp | Exponent of the unit.

Returns
  The exponent of the prefix.

void DecimalPrefix::setExponent | ( | int | iexp | ) |

Sets the exponent of the prefix.

Parameters

  iexp | New exponent for the prefix.

int DecimalPrefix::type | ( |  | ) | const
| virtual

Returns
  The type of the prefix.

Implements Prefix.

Number DecimalPrefix::value | ( | const Number & | nexp | ) | const
| virtual

Returns the value of the prefix.

Parameters

  nexp | The power of the prefixed unit.

Returns
  The value of the prefix.

Implements Prefix.

Number DecimalPrefix::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 DecimalPrefix::value | ( |  | ) | const
| virtual

Returns the value of the prefix.

Returns
  The value of the prefix.

Implements Prefix.
