For example, an expression like will be uint8 (because of the rules of concatenating integers of different sizes) with the larger values truncated (because of the saturation semantics of integer values). Note that this may cause problems in existing code. Binary constants are limited to 64 binary digits and hexadecimal constants are limited to 16 hexadecimal digits with no automatic rounding or conversion to floating point values. You may also use a suffix of the form u8, u16, u32, u64, s8, s16, s32, or s64 to explicitly specify the data type to use (u or s to indicate unsigned or signed and the number to indicate the integer size). For example, 0xff creates a uint8 value and 0xDEADBEEF creates a uint64 value. Binary and hexadecimal constants like 0b101 and 0xDEADBEEF now create integers (unsigned by default) with sizes determined from the number of digits present. Typically, code blocks like the following can simply be deleted. Existing code can be simplified by removing these checks which are now done by the interpreter. Input validation for functions typically begins with checking that the number of inputs and outputs match expectations. If a function uses varargin then the check is skipped for function inputs, and if a function uses varargout then the check is skipped for function outputs. The interpreter makes this check automatically. Calling a user-defined function with too many inputs or outputs is now an error. Many functions in Octave can be called in a command form-no parentheses for invocation and no return argument assignment-or in a functional form-parentheses and ‘=’ for assignment of return values.
