# unsigned

unsigned(x) -> Unsigned

Convert a number to an unsigned integer. If the argument is signed, it is reinterpreted as unsigned without checking for negative values.

## Examples

Here are some examples of how to use the `unsigned` function in Julia:

1. Convert a signed integer to an unsigned integer:

``````julia> signed_int = -10;
julia> unsigned_int = unsigned(signed_int)
18446744073709551606``````

This example converts the signed integer `-10` to an unsigned integer using the `unsigned` function.

2. Convert a float to an unsigned integer:

``````julia> float_num = 3.14;
julia> unsigned_int = unsigned(float_num)
3.14``````

The `unsigned` function can also be used to convert a floating-point number to an unsigned integer. However, the result will be the same as the original float since `unsigned` does not perform any type conversion for non-integers.

3. Convert a negative signed integer to an unsigned integer:
``````julia> negative_int = -100;
julia> unsigned_int = unsigned(negative_int)
18446744073709551516``````

The `unsigned` function reinterprets the negative signed integer `-100` as an unsigned integer without checking for negative values. The resulting unsigned integer may not be the same as the original signed value.

Common mistake example:

``````julia> unsigned("10")
ERROR: MethodError: no method matching unsigned(::String)``````

In this example, the `unsigned` function cannot convert a string to an unsigned integer. It is important to ensure that the argument passed to `unsigned` is a numerical value that can be converted to an unsigned integer.
