Exception for Diagrams.Solve.Polynomial:quartForm from diagrams-solve-0.1, C

Math

\[\left(\left(x \cdot y + \frac{z \cdot t}{16}\right) - \frac{a \cdot b}{4}\right) + c\]

C

double code(double x, double y, double z, double t, double a, double b, double c) {
	return ((double) (((double) (((double) (((double) (x * y)) + ((double) (((double) (z * t)) / 16.0)))) - ((double) (((double) (a * b)) / 4.0)))) + c));
}
