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