DEGREES function
Degrees function. DEGREES(x) converts an angle x expressed in radians to degrees.
The relation between the two units is: 2 radians = 360 degrees, giving the conversion formula:
$$ \text{DEGREES}(x) = x \times \frac{180}{\pi} $$
The argument x can be a real number or a matrix. When it is a matrix, the function returns a matrix with the same dimensions and with the DEGREES function applied to all elements.
Examples
DEGREES(PI()/2) equals 90.
DEGREES(PI()) equals 180.
