Numerical Analysis Questions & Answers  
Please ask your questions related to Numerical Analysis in this thread, I will answer them as soon as possible. To insert mathematics use LATEX. For instance, let's say we wish to insert math within a sentence such as $C_f$ is equal to $\tau_w /\frac{1}{2} \rho q_\infty^2 $. This can be done by typing \$C_f\$ is equal to \$\tau_w /\frac{1}{2} \rho q_\infty^2\$. Or, if you wish to display an equation by itself out of a sentence such as: $$ \frac{d}{dt}\int_V \rho dV + \int_S \rho (\vec{v} \cdot \vec{n}) dS =0 $$ The latter can be accomplished by typing \$\$\frac{d}{dt}\int_V \rho dV + \int_S \rho (\vec{v} \cdot \vec{n}) dS =0\$\$. You can learn more about LATEX on tug.org. 



No attached pictures are allowed in the QNA thread except if they are drawings. The mathematics must be typeset within your question using LATEX, not using pictures.




You haven't read correctly my response to your question. To give you more time to think carefully about how to formulate a question using LATEX, you are now limited to one new question every 7 days.




I don't understand the question fully. If I ask for the smallest positive number, then this can not be zero whether the number is normal or denormal because zero is not positive. I'll give you just 0.5 point bonus boost because you should put your question in more context so that I can understand better what you mean.




When using float variables in C, $\epsilon_{\rm mach}$ should be set to $6\times 10^{8}$. But I won't take away points if you use a slightly more conservative value of $10^{7}$. The order of magnitude is what counts here. It was a good question, I'll give you 1.5 points bonus boost for it.
