I have written a std code for ARM 32-bit platform using math.h library and float=powf(float,float) function. When I give input to my system as 100 ^ 4.4 it gives me answer as 630957632.0000 (as float) whereas calculator in WindowsXP gives answer as 630957344.48019324943436013662234.
I just want to know which one is more accurate ???? why is difference ????? on what things accuracy depends???? Also what do we mean by "arbitrary"-precision??? I have read such word on MSDN help forums. how much accurate is my system???? how to improve accuracy?????? Thanks in advance!!!!!!!!!!! -- View this message in context: http://gcc.1065356.n5.nabble.com/powf-float-float-function-from-math-h-on-ARM32-bit-platform-tp956727.html Sent from the gcc - Dev mailing list archive at Nabble.com.
