arccos_deg¶
Description¶
Computes the arc cosine of the input. The result is a float64, specified in degrees, in the range [0, 180]
Arguments
input (required) Ratio to find the arc cosine of, float64. Must be in the range [-1, 1], otherwise the function returns null.
Return type¶
float64
Domain¶
This is a scalar function (calculates a single output value for a single input row.)

Examples¶
make_col arccos:arccos_deg(ratio)
Create a column ‘arccos’ with the result of the arc cosine of column ‘ratio’
The resulting column will be in degrees.
Given the below column ratio
, arccos_deg
produces the below column arccos
Ratio should be a floating point number and in the range [-1, 1]. Any inputs outside this range have the result null.
