function DataType = sint( TotalBits );
%SINT Create structure describing Signed INTeger data type
%
%    This data type structure can be passed to the 
%    Fixed Point Blockset.
%
%    SINT( TotalBits )
%
%    For example, SINT(16) returns a MATLAB structure
%    that describes the data type of a 
%    16 bit Signed INTeger number.
%
%    Note: for integer types, the radix point is just
%    to the right of all bits.
%
%    See also SFIX, UFIX, UINT, SFRAC, UFRAC, FLOAT.
