I\'ve been tasked with writing a simple application in mixed C/ASM that has to use math co开发者_Go百科processor.
I am trying to convert an 80-bit extended precision floating point number (in a buffer) to double. The buffer basically contains the content of an x87 register.
What are the best settings for stuff like MXCSR? Which rounding mod开发者_运维技巧e is fastest? On what processors? Is it faster to enable signalling NaNs so I get informed when a computation results
I\'m trying to get a basic understanding of floating point operations on x86. I understand that we have a dedicated FPU wit开发者_如何学Goh a stack, but I\'m not finding much relevant information on h

I\'m somewhat familiar with the x87 instructions for manipulating floating point numbers in x86 assembly. However, I read somewhere that these were seldom used anymore. (And weren\'t allowed in 64-bit
I was reading today about researchers discovering that NVidia\'s Phys-X libraries use x87 FP vs. SSE2. Obviously this will be suboptimal for parallel datasets where speed trumps precision. However, th
I\'ve recently read up quite a bit on IEEE 754 and the x87 architecture.I was thinking of using NaN as a \"missing value\" in some numeric calculation code I\'m working on, and I was hoping that using
