Computes the radians of an input value measuring degrees of= an angle. The value can be a Decimal or Integer literal or a reference to = a column containing numeric values.
• A unit of 1 radian identifies the angle of a circle wh= ere the radius of the circle equals the length of the arc on the circle for= that angle. This value corresponds to approximately 57.3 degrees.
• Input units are in degrees.

## Basic Usage

Numeric literal example:

=20

Output: Generates a column containing the computation i= n radians of `57.2728` rounded to four digits, which is ```1.= 0000```.

Column reference example:

=20

Output: Generates the new `myRads` column co= ntaining the conversion of the values in `MyDegrees` column to r= adians.

## Synt= ax and Arguments

Argument Required? Data Type Description
numeric_value Y string, decimal, or integer Name of column, Decimal or Integer literal, or f= unction returning those types to apply to the function

### numeric_value

Name of the column, Integer or Decimal literal, or function returning th= at data type to apply to the function.

• Missing input values generate missing results.
• Literal numeric values should not be quoted. Quoted values are treated = as strings.
• Multiple columns and wildcards are not supported.

Required? Data Type Example Value
Yes String (column reference) or Integer or Decimal = literal `10`

## Examples

### Example - DEG= REES and RADIANS functions

This example illustrates to use the DEGREES and RADIANS functions to con= vert values from one unit of measure to the other.

Source:

In this example, the source data contains information about a set of iso= sceles triangles. Each triangle is listed in a separate row, with the liste= d value as the size of the non-congruent angle in the triangle in degrees.<= /p>

You must calculate the measurement of all three angles of each isosceles= triangle in radians.

=20 =20 =20
triangle a01
t01 30
t02 60
t03 90
t04 120
t05 150

Transform:

You can convert the value for the non-congruent angle to radians using t= he following:

=20

derive type:single value: ROUND(RADI= ANS(a01), 4) as: 'r01'

Now, calculate the value in degrees of the remaining two angles, which a= re congruent. Since the sum of all angles in a triangle is 180, the followi= ng formula can be applied to compute the size in degrees of each of these a= ngles:

=20

derive type:single value: (180 - a01= ) / 2 as: 'a02'

=20

derive type:single value: ROUND(RADI= ANS(a02), 4) as: 'r02'

Create a second column for the other congruent angle:

=20

derive type:single value: ROUND(RADI= ANS(a02), 4) as: 'r03'

To check accuracy, you sum all three columns and convert to degrees:

= =20

derive type:single value: ROUND(DEGR= EES(r01 + r02 + r03), 4) as: 'checksum'

Results:

After you delete the intermediate columns, you see the following results= and determine the error in the checksum is acceptable:

=20 =20 =20 =20 =20 =20 =20
triangle a01 r03 r02 r01 checksum
t01 30 1.3095 1.3095 0.5238 179.9967
t02 60 1.0476 1.0476 1.0476 179.9967
t03 90 0.7857 0.7857 1.5714 179.9967
t04 120 0.5238 0.5238 2.0952 179.9967
