How to write ln(x) C programming

I'm trying to write the Steinhart - Hart Equation formula 1 / T = A + B(Ln R ) + C(Ln R )3 in C language but i don't know the math function for Ln.

Anyone know?

Natural log is "log(x)", log to base 10 is "log10(x)" I think.

Click to expand...

if you are using the basic iostream library with
Code: 
using namespace std;

log(x) should do for "ln(x)"
and
log10(x) should do for the base 10 log.

I hope that answered the question.
