This functionperforms the same operation as the Binary Exponentiation operator (**). (See Operators inUsing Caché ObjectScript.)ParametersnumThe number to be raised to a power. It can be integer or floating point, negative, positive, orzero. It can be specified as a value, a variable, or an expression.
