`float` (32-bit) and `double` (64-bit) with + - * / %, comparisons and unary minus. Decimal literals take their type from context and stay `fixed` elsewhere; int and long promote implicitly (LUDIC_WARN_FLOAT_PROMOTE=1 lists every promotion). float(), double(), int(), long() and fixed() convert; floats(n)/doubles(n) buffers; float fields, globals, constants and parameters; Math.* computes in float for float arguments; string/print write the shortest round-tripping decimal; float_bits/float_from_bits expose the bits. @deterministic code may not use floats. The f_* runtime helpers stay as they are. Editors know the new type words; the JetBrains plugin is 1.5.0. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>

Deterministic fixed-point math. Every function is computed in Q16.16 with plain integer arithmetic, so results are bit-identical on every platform and every run — the same guarantee the rest of the runtime gives. Arguments are positional.
Given a float or double argument, the same functions compute in that type instead (using the platform's math library) and return it — floor, ceil and round included, which return an int only for fixed. sign returns an int either way. trunc and atan exist only for floats.
