RADIANS function

Overview

RADIANS is a function of the Math and Trigonometry category that converts an angle measured in degrees to an equivalent angle measured in radians.

Usage

Syntax

RADIANS(angle) => radians

Argument descriptions

• angle (number, required). The angle in degrees that is to be converted to radians.

Additional guidance

The conversion from degrees to radians is based on the relationship:

$$1\text{degree}={\displaystyle \frac{\pi }{180}}\text{radians}\approx 0.01745329252\text{radians}$$

Returned value

RADIANS returns a number that represents the value of the given angle expressed in radians.

Error conditions

• In common with many other IronCalc functions, RADIANS propagates errors that are found in its argument.
• If no argument, or more than one argument, is supplied, then RADIANS returns the #ERROR! error.
• If the value of the angle argument is not (or cannot be converted to) a number, then RADIANS returns the #VALUE! error.
