Round-off Error

Loren recently posted a simple example of how single-threaded computations might produce different results from multi-threaded computations.  The cause is floating-point round off, and most people are surprised to learn that the "different" results actually agree!  In this post, I want to explore this same example in 亚搏国际网页.... read more >>

Floating-Point Numbers 6

Numeric simulation is all about the numbers.  In a previous post, I talked about integer and fixed-point number representations.  These numbers are especially useful for discrete simulation and embedded systems.  For continuous dynamic systems, the values do not represent discrete values but continuously changing functions in time.  For this, floating-point numbers provide the flexibility and range... read more >>

How do I test for NaN in 亚搏国际网页 R2009b? (NEW!) 2

Back in February 2009 I posted about how to test for NaN in 亚搏国际网页.  The approach I talked about was more of a logical experiment based on the special properties of NaN than an ideal software solution.  In 亚搏国际网页 R2009b the Relational Operator block got an upgrade to include isNaN.  Let’s see how it... read more >>
