public protocol ElementaryFunctions
A type that has elementary functions available.
An “elementary function” is a function built up from powers, roots, exponentials, logarithms, trigonometric functions (sin, cos, tan) and their inverses, and the hyperbolic functions (sinh, cosh, tanh) and their inverses.
Conformance to this protocol means that all of these building blocks are available as static functions on the type.
let x: Float = 1
let y = Float.sin(x) // 0.84147096
-
The square root of
x
.For real types, if the argument is negative, either the result is NaN or a precondition failure occurs. For complex types, this function has a branch cut along the negative real axis.
