     20  * rs_math.rsh: Mathematical Constants and Functions
     21  *
     22  * The mathematical functions below can be applied to scalars and vectors.   When applied
     23  * to vectors, the returned value is a vector of the function applied to each entry of the input.
     24  *
     25  * For example:
     26  * float3 a, b;
     27  * // The following call sets
     28  * //   a.x to sin(b.x),
     29  * //   a.y to sin(b.y), and
     30  * //   a.z to sin(b.z).
     31  * a = sin(b);
     32  *
     33  *
     34  * See Vector Math Functions for functions like distance() and length() that interpret
     35  * instead the input as a single vector in n-dimensional space.
     36  *
     37  * The precision of the mathematical operations on 32 bit floats is affected by the pragmas
     38  * rs_fp_relaxed and rs_fp_full.  Under rs_fp_relaxed, subnormal values may be flushed to zero and
     39  * rounding may be done towards zero.  In comparison, rs_fp_full requires correct handling of
     40  * subnormal values, i.e. smaller than 1.17549435e-38f.  rs_fp_rull also requires round to nearest
     41  * with ties to even.
     42  *
     43  * Different precision/speed tradeoffs can be achieved by using variants of the common math
     44  * functions.  Functions with a name starting with
     45  * - native_: May have custom hardware implementations with weaker precision.  Additionally,
     46  *   subnormal values may be flushed to zero, rounding towards zero may be used, and NaN and
     47  *   infinity input may not be handled correctly.
     48  * - half_: May perform internal computations using 16 bit floats.  Additionally, subnormal
     49  *   values may be flushed to zero, and rounding towards zero may be used.
