+ For real x, let {x}_P or x_P be the closest representible number in the
+ floating point representation which uses P binary bits of fractional
+ precision (with IEEE rounding semantics).
+
+ Similarly, let f_P(x) be shorthand for {f(x)}_P.
+
+ Let ulp_P(x) be the unit of least precision for x: in other words the
+ maximal value of |a_P - b_P| where a_P <= x <= b_P and a_P != b_P.
+
+ Let x ~= y <-> | x - y | < ulp_P(x - y).
+
+ Let deg(x) be the value of x radians in degrees.
+
+ Values for each precision P were selected as follows.
+
+
+ COSD_SMALL = 2**{-N} such that for all x <= COSD_SMALL:
+
+ * cos(deg(x)) ~= 1, or equivalently:
+
+ | 1 - cos(deg(x)) | < ulp_P(1).
+
+ Unfortunately for SIND (and therefore TAND) a similar relation is only
+ possible for REAL(4) and REAL(8). With REAL(10) and REAL(16), enough
+ precision is available such that sin_P(x) != x_P for some x less than any
+ value. (There are values where this equality holds, but the distance has
+ inflection points.)
+
+ For REAL(4) and REAL(8), we can select SIND_SMALL such that:
+
+ * sin(deg(x)) ~= deg(x), or equivalently:
+
+ | deg(x) - sin(deg(x)) | < ulp_P(deg(x)).

+This file is included from both the FE and the runtime library code.
+Operations are generalized using GMP/MPFR functions. When included from

+be used as-is.
+
+The following macros and GMP/FMPR functions are used and must be defined.
+
+
+Types and names:
+
+FTYPE
+ Type name for the real-valued parameter.
+ Variables of this type are constructed/destroyed using mpfr_init()
+ and mpfr_clear.
+
+RETTYPE
+ Return type of the functions.
+
+RETURN(x)
+ Insert code to return a value.
+ The parameter x is the result variable, which was also the input parameter.
+
+ITYPE
+ Type name for integer types.
+
+SIND, COSD, TRIGD
+ Names for the degree-valued trig functions defined by this module.
+
+
+Literal values:
+
+TINY [optional]
+ Value subtracted from 1 to cause rase INEXACT for COSD(x)
+ for x << 1. If not set, COSD(x) for x <= COSD_SMALL simply returns 1.
+
+COSD_SMALL [optional]
+ Value such that x <= COSD_SMALL implies COSD(x) = 1 to within the
+ precision of FTYPE. If not set, this condition is not checked.
+
+SIND_SMALL [optional]
+ Value such that x <= SIND_SMALL implies SIND(x) = D2R(x) to within
+ the precision of FTYPE. If not set, this condition is not checked.
+
+COSD30
+ Value of SIND(60) and COSD(30).
