I\'m trying to calculate logab (and get a floating point back, not an integer). I was planning to do this as log(b)/log(a). Mathematically sp开发者_如何转开发eaking, I can use any of the cmath log fun
Hey so i managed to locate the problem in some graphics math i am coding, and apparently when i reach this line of code: float test3= asin(test2); where test2= 0.017409846.
Hey so i\'m doing some graphics math and inserting what i believe to be a float (i\'m pretty sure the ways i manipulate the float beforehand is messing something up开发者_StackOverflow中文版 somehow..
I used to work with math.h without any problem. Now, I use an external library which itself has a file called math.h, but which includes < cmath>.

I assume that abs and fabs are behaving different when using math.h. But when I use just cmath and std::abs, do I ha开发者_运维问答ve to use std::fabs or fabs? Or isn\'t this defined?In C++, it\'s alw
must you convert from strings to double? if so. how? Are there functions for trig that will 开发者_运维百科accept textbox string data as is?
