<p>The value for a is not restricted to the range [0, 1].</p>
<p>If genTypeU is a boolean scalar or vector: Selects which vector each returned component comes from. For a component of that is false, the corresponding component of x is returned. For a component of a that is true, the corresponding component of y is returned. Components of x and y that are not selected are allowed to be invalid floating point values and will have no effect on the results. Thus, this provides different functionality than genType mix(genType x, genType y, genType(a)) where a is a Boolean vector.</p>

<p>Returns a value equal to the nearest integer to x. </p>
<p>The fraction 0.5 will round in a direction chosen by the implementation, presumably the direction that is fastest. This includes the possibility that round(x) returns the same value as roundEven(x) for all values of x.</p>
<p>Returns 0.0 if x <= edge0 and 1.0 if x >= edge1 and performs smooth Hermite interpolation between 0 and 1 when edge0 < x < edge1. </p>
<p>This is useful in cases where you would want a threshold function with a smooth transition. This is equivalent to: genType t; t = clamp ((x - edge0) / (edge1 - edge0), 0, 1); return t * t * (3 - 2 * t); Results are undefined if edge0 >= edge1.</p>
<p>Returns a floating-point value corresponding to a unsigned integer encoding of a floating-point value. </p>
<p>If an inf or NaN is passed in, it will not signal, and the resulting floating point value is unspecified. Otherwise, the bit-level representation is preserved.</p>
