For an example of using the atan2 function to find an angle in the image,
refer to the Math Tool Formula Examples section on page 7–137.
dgrs –– The “ dgrs ” (degrees) function converts radians to degrees on the
basis of the radian value that you enter after the opening parenthesis. Thus, if
you enter
dgrs(3.14159) as a formula, and then pick the Nominal field in
the tool edit panel, 180.000 will appear in the Nominal field, indicating that
3.14159 radians was converted to 180.000 degrees.
rads –– The “ rads ” (radians) function converts degrees to radians on the
basis of the degree value that you enter after the opening parenthesis. Thus, if
you enter
rads(180) as a formula, and then pick the Nominal field in the
tool edit panel, 3.142 will appear in the Nominal field, indicating that 180
degrees was converted to 3.142 radians.
