arcsin_rad

Description

Computes the arc sine of the input. The result is a float64, specified in radians, in the range [-$\pi$/2, $\pi$/2]

Arguments

  1. input (required) Ratio to find the arc sine 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 arcsin:arcsin_rad(ratio)

Create a column ‘arcsin’ with the result of the arc sine of column ‘ratio’
The resulting column will be in radians.

Given the below column ratio, arcsin_rad produces the below column arcsin
Ratio should be a floating point number and in the range [-1, 1]. Any inputs outside this range have the result null.
