nx_mathspec_sincos.nx

nx_mathspec_sincos.nx -- SOVEREIGN SPEC EMITTER (the role python generators held, now a team organ): computes every SINCOS kernel constant on the 120-bit bigfloat and writes the _pm_sin_spec.nx data module the MATH_KERNEL emitter consumes. - 2/pi (f64) - 3-part pi/2 split: HI/MID keep 32 effective mantissa bits (low 21 zeroed) so k*HI and k*MID are EXACT for |k| <= 2^21; LO = f64 remainder. - sin coeffs (-1)^k/(2k+1)!, k=0..9 and cos coeffs (-1)^k/(2k)!, k=0..9 NEGATIVE literals are emitted in `0 - N` form (unary-minus literal landmine). Layout: c[0]=2/pi c[1]=HI c[2]=MID c[3]=LO c[4]=half c[5]=one c[6..15] sin coeffs HI-FIRST (a9..a0) c[16..25] cos coeffs HI-FIRST license_tier: ORIGINAL
