Function atan2

Calculate the inverse tangent function with two arguments, y/x. By providing two arguments, the right quadrant of the computed angle can be determined.

For matrices, the function is evaluated element wise.

Syntax

math.atan2(y, x)

Parameters

Parameter	Type	Description
`y`	number \| Array \| Matrix	Second dimension
`x`	number \| Array \| Matrix	First dimension

Returns

Type	Description
number \| Array \| Matrix	Four-quadrant inverse tangent

Throws

Examples

math.atan2(2, 2) / math.pi       // returns number 0.25

const angle = math.unit(60, 'deg') // returns Unit 60 deg
const x = math.cos(angle)
const y = math.sin(angle)

math.atan(2)             // returns Complex 1.5707963267948966 -1.3169578969248166 i
