exp(+Number, -Result)
-Result is exp(+Number)

   Evaluates the exponential function exp(Number) ("e to the power of Number")
and unifies the resulting value with Result.



Arguments
   Number              A number.
   Result              Output: float or breal.

Type
   Arithmetic

Description

   Evaluates the exponential function exp(Number) ("e to the power of Number")
   and unifies the resulting value with Result.

   This predicate can be used as a function in arithmetic expressions.
   In coroutining mode, if Number is uninstantiated, the call to exp/2 is
   delayed until this variable is instantiated.




Modes and Determinism
   exp(+, -) is det

Exceptions
     4 --- Number is not instantiated (non-coroutining mode only).
    24 --- Number is not of a numeric type.

Examples
   
    Result is exp(0.0).       % gives Result = 1.0
    Result is exp(-6).        % gives Result = 0.00247875
