Thread: Function help

So i made a simple function to get the absolute value of a float type number because the abs() function outputs integer numbers.

When i compiled the program, an error message popped out.

"Error: Conflicting types for 'absf'"

Code:

float absf(float x)
{
	if(x<0)
	{
		x=-x;
	}
	return x;
}

If you don't have a prototype for the function, above main(), and absf() is listed in the code below main(), then C will use it's own default prototype for absf() - which would be wrong, in this case (it assumes an int parameter, and an int return).
