Now that you have seen the complete line of C++ integer types, let's look at the floating-point types, which compose the second major group of fundamental C++ types. These numbers let you represent numbers with fractional parts, such as the gas mileage of an M1 tank (0.56 MPG). They also provide a much greater … WebIn a system level programming language like C, C++ or D, what is the best type/encoding for storing latitude and longitude? The options I see are: IEEE-754 FP as degrees or radians degrees or radians stored as a fixed point value in an 32 or 64 bit int mapping of an integer range to the degree range: -> deg = (360/2^32)*val
