Types
Type-synonyms
type Exponential base exponent = (base, exponent) Source
Describes an exponential, in terms of its base and exponent.
Functions
evaluate :: (Num base, Integral exponent) => Exponential base exponent -> base Source
Evaluate the specified Exponential, returning the resulting number.
invert :: Num exponent => Exponential base exponent -> Exponential base exponent Source
Invert the value, by negating the exponent.
Accessors
getBase :: Exponential base exponent -> base Source
Accessor.
getExponent :: Exponential base exponent -> exponent Source
Accessor.
Constructors
rightIdentity :: Num exponent => base -> Exponential base exponent Source
- Construct an
Exponentialmerely raised to the 1st power. - The value of the resulting exponential is the same as specified
base; http://en.wikipedia.org/wiki/Identity_element.
Operators
Arguments
| :: Num exponent | |
| => Exponential base exponent | The operand. |
| -> exponent | The power to which the exponential is to be raised. |
| -> Exponential base exponent | The result. |
Raise the specified Exponential to a power.
(=~) :: Eq base => Exponential base exponent -> Exponential base exponent -> Bool infix 4 Source
True if the bases are equal.
