Matrix.h conversion from degrees to radians

I'm reading through this project to help with my own OpenGL project and I noticed line 180 of matrix.c:
ymax = znear * tanf(fov * PI / 360.0);
Is fov in degrees? If so the correct way to convert it to radians would be:
ymax = znear * tanf(fov * PI / 180.0);

Yes, FOV is in degrees. The argument passed to tanf is half of the FOV.
