import RealModuleprotocol RealFunctions : ElementaryFunctionsstatic func _mulAdd(_ a: Self, _ b: Self, _ c: Self) -> Self a*b + c, computed either with an FMA or with separate multiply and add.
static func atan2(y: Self, x: Self) -> Self atan(y/x), with sign selected according to the quadrant of (x, y).
static func erf(_ x: Self) -> Self The error function evaluated at x.
static func erfc(_ x: Self) -> Self The complimentary error function evaluated at x.
static func exp10(_ x: Self) -> Self 10^x
static func exp2(_ x: Self) -> Self 2^x
static func hypot(_ x: Self, _ y: Self) -> Self sqrt(x*x + y*y), computed in a manner that avoids spurious overflow or underflow.
