I wanted to get 54321 but instead got this for some reason a 1 is getting removed in the 3rd and last loop.

    `m += pow(10,i)*temp;` Don't use floating points in integer calculations where you expect exact results. – dxiv Feb 04 '21 at 06:00

    I switched the pow for a command I wrote myself that does the same thing and it worked. It seems like using pow from cmath causes this problem so I wanted to know why that happens. – Joelcantcode Feb 04 '21 at 06:08
