off topic, but since it seems that so many of you guys know programming, maybe you can help me! (On topic in the way that one day when I am proficient in c, I may become a kernel hacker....) Real simple question but I am pretty much a beginner here: How would I write a function in c be to convert from st input a binary number to output a base ten number? 10101111 entered would be output 175 or 1.75 x 10^2. (Or does this function exist, but I don't know it?) I know it has to be easy but still been spending about an hour now with incorrect results. Thanks
Wanting someone to do your school work for you, heh? (An old teacher can spot these attempts.!) Your problem isn't coding, it is understanding base conversion math. 7 6 5 4 3 2 1 0 N = 1*2 + 0*2 + 1*2 + 0*2 + 1*2 + 1*2 + 1*2 + 1*2 10 7 6 5 4 3 2 1 0 N = h*2 + g*2 + f*2 + e*2 + d*2 + c*2 + b*2 + a*2 10 See the pattern? Can you write a loop that indexes from 0 to 7, parses a binary number, hgfedcba, and sums the terms? JLK On Saturday 27 January 2001 21:23, s smith wrote:
