Oracle EXP() function
Description
The Oracle EXP() function is used to get the value of the base of natural logarithm number e, raised to the power of a number specified as argument, where e ≈ 2.71828183.
The function takes any numeric or nonnumeric data type (can be implicitly converted to a numeric data type) as an argument.
If the argument is BINARY_FLOAT, then the function returns BINARY_DOUBLE. Otherwise, the function returns the same numeric data type as the argument.
Uses of Oracle EXP() Function
