Convert an object from one data type to another.
typecast (x, new_type)
The typecast function performs a generic typecast operation on
x to convert it to new_type. If x represents an
array, the function will attempt to convert all elements of x
to new_type. Not all objects can be converted and a
type-mismatch error will result upon failure.
define to_complex (x)
{
return typecast (x, Complex_Type);
}

number.
