Optimizing pow() function

I have a simple (16-bit) embedded platform and I have to make the following calculations. unsigned int func(unsigned int adc, unsigned int pwr, unsigned int pt, double exp) { return (unsigned int)(pow((double)adc, exp) * (double)pwr / pow((double)pt, exp)); ... I noticed this calculation takes too much time, most probably for pow() function call and double conversion.... more » By pozzu...@gmail.com  - Apr 22 - 51 new of 51 messages

comp.lang.c

... ... That's normally supported via wchar_t. As has been pointed out elsewhere, in spite of the name, a "char" isn't necessarily a character. The semantics of "char" appear to be designed around the assumption that it's a byte, i.e. the hardware's unit of addressable memory. AFAICT, all general-purpose microprocessors use an 8-bit byte, and thus so... more » By M.gowtham M.gowtham  - Apr 22 - 11 new of 11 messages

	short int always 16 bits or not?
	Hello. I am reading the C99 standard as available from: [link] I note that it specifies (on p 34) macros defining the minimum and maximum values of a short int corresponding to a size of 16 bits. However it doesn't explicitly say that short int-s should be of 16 bits size. So can I trust short int-s to be 16 bits size or not?... more » By Shriramana Sharma  - Apr 19 - 34 new of 34 messages

Who can explain this bug?

Platform: gcc 4.6.3 on AMD Athlon(tm) II X2 245 Processor on Ubuntu 12.04 The bug I thought was due to a particularly hard to find memory access problem (see other thread I started today) seems to be even odder than that. It was tracked down to a particular conditional, which seems to optimize in such a way that the result is not always correct. (But... more » By mathog  - Apr 17 - 65 new of 65 messages
