— perf(fsltype): format a 53-bit text Julian day in float64, no math/big
Fossil's %.17g of a text Julian day is computed in the platform's long double, which this package emulates with big.Float at that precision. A 53-bit long double is a double, and big.Float at 53 bits with round-to-nearest-even is exactly IEEE double arithmetic over this range, so that case (wasm, macOS arm64, Windows) is now computed in float64, each product converted explicitly so none fuses into a multiply-add.
The big.Float path remains for the 64- and 113-bit long doubles and is left out of wasm builds, whose long double is 53 bits; a wasm TinyGo binary loses math/big's floating point, about 5 KB gzipped. A test checks the float64 path against the big.Float one at 53 bits over 50,000 random times and every ~1 s of three days, and the existing fossil-binary sweep passes unchanged. Stored times do not change. (user: [email protected], size: 359) [annotate] [blame] [check-ins using]
