int | exp |
A metric or decimal prefix has an integer exponent which with a base of ten constitutes the value of the prefix (value=10^exponent).
DecimalPrefix::DecimalPrefix | ( | int | exp10, | |
string | long_name, | |||
string | short_name = "" , |
|||
string | unicode_name = "" | |||
) |
Create a decimal prefix.
exp10 | Exponent for the value. | |
long_name | Long name. | |
short_name | Short name. | |
unicode_name | Unicode name. |
int DecimalPrefix::exponent | ( | int | iexp = 1 |
) | const |
Returns the exponent.
iexp | Exponent of the unit. |
Returns the exponent.
nexp | Exponent of the unit. |
void DecimalPrefix::setExponent | ( | int | iexp | ) |
Sets the exponent of the prefix.
iexp | New exponent for the prefix. |
Returns the value of the prefix.
nexp | The power of the prefixed unit. |
Implements Prefix.
Number DecimalPrefix::value | ( | int | iexp | ) | const [virtual] |
Returns the value of the prefix.
iexp | The power of the prefixed unit. |
Implements Prefix.
Number DecimalPrefix::value | ( | ) | const [virtual] |
int DecimalPrefix::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.
Implements Prefix.
