Re: Doubt Regarding Floating Point Arithmetic
Can you please explain me one scenario that lets suppose take calculator application in lower level it should interact with kernel code So here who is take care of Floating point calculations? Sorry if i am wrong Thanks for replying me On 23 July 2014 08:45, me storage <me.storage126@gmail.com> wrote:
Hi I am reading LDD .In that i didn't understand one point .In Chapter 2(Building and Running Modules) they mentioned that " Kernel code cannot do floating point arithmetic" .My doubt is which code is used for floating point arithmetic that means at low level?
Thank you

The userspace program does the floating point calculations. The kernel would not interact with a calculator application in a way that would require the kernel to do anything here, it merely schedules the userspace tasks to run. Hope this helps, greg k-h
