This function displays the IEEE double-precision representation of a double in MATLAB. If used with the Symbolic Math Toolbox, it can also display the exact number represented by that IEEE floating point number (which may not be exactly the same as the input; see the Fall 1996 Cleve's Corner article at https://www.mathworks.com/content/dam/mathworks/mathworks-dot-com/company/newsletters/news_notes/pdf/Fall96Cleve.pdf )
