Question

So I’m trying to figure out the best way to solve simple logarithms using objective c. For example ln 30 = 3.4012. I’m not too sure if there’s any built in functionality in objective c to do this. Any ideas?

Answer 1

In fact it is “c” question because Objective-C is based on c, and all primitive math functions like logarithms are included in math.h
so use:

log() to find logarithms

exp() to find exponent
e.g.

NSLog(@"log(30.0):%f", log(30.0));
NSLog(@"exp(3.4012):%f", exp(3.4012));

>

log(30.0):3.401197
exp(3.4012):30.000079
