I have been lately working on a problem and I have noticed that pow() function gives me sometimes a wrong number. $\newline$ Here's an example : $\newline$ I wanted to calculate $3^{38}$ : The calculator indicates that it is equal to 1350851717672992089. However, when I executed the command pow(3,38); I got this number instead : 1350851717672992000. $\newline$ Can anyone explain to me why is this happening and how to fix it ?
