acos

expect fun acos(x: Double): Double(source)
expect fun acos(x: Float): Float(source)

Computes the arc cosine of the value x; the returned value is an angle in the range from 0.0 to PI radians.

Special cases: - acos(x) is NaN, when abs(x) > 1 or x is NaN

Since Kotlin

1.2
actual inline fun acos(x: Double): Double(source)

Computes the arc cosine of the value x; the returned value is an angle in the range from 0.0 to PI radians.
