Mathematical

## Summary:

Converts an angle expressed in degrees to radians.

## Returns:

Returns a real number which is the value of the given angle converted to radians.

## Arguments:

Number is a real number, or a reference to the cell containing that number, that is the angle in degrees to be converted to radians.

• If Number is non-numeric, then RADIANS reports a #VALUE! error.

• 1 radian is equivalent to approximately 57.2957795130823 degrees.
• The function implements the formula $\displaystyle{ \text{RADIANS}(x)~=~x * \frac{\pi }{180} }$.

## Examples:

Formula Description Returns
=RADIANS(57.2957795130823) Convert 57.2957795130823 degrees to radians. 1
=RADIANS(D1) where cell D1 contains the number 180. Convert 180 degrees to radians. 3.14159265358979 (π)
=RADIANS(720) Convert 720 degrees to radians. 12.5663706143592 (4π)
=RADIANS(-45) Convert -45 degrees to radians. -0.785398163397448 (-π/4)
