Question

I have this line of code:

int g = modf(ans*power, 1)*10;

And it is giving me the error:

Invalid conversion from ‘int’ to ‘double*’.

ans is defined as:

double ans = 1.0/d;

power is defined as:

int power = pow(10,x);

and the x that power is using is defined as:

for(int x = 0; x < 50; x++) {

I don’t see where I am using a pointer. If you need more code just ask.

(I have also tried making the line of code that causes the error:

int g = (int)modf(ans*power, 1)*10;

but that did not work either).

Answer 1

modf(ans*power, 1) is bad

double smthng = 1.0; modf(ans*power, &smthng) is good.
