De-abbreviate the two bare fixed-point conversion builtins:
flr(f) -> int -> floor(f) -> int (fixed -> int, flooring)
fx(i) -> fixed -> fixed(i) -> fixed (int -> fixed; mirrors how the
stringify builtin is `string`)
Updates the compiler dispatch, all call sites, the grammars/LSP/JetBrains
tokens, and the docs (fn-flr -> fn-floor, fn-fx -> fn-fixed). Reseeded;
C-free fixpoint holds; all suites green (45/24/29); site + check.py OK.

| fn-fixed | fixed | builtins | builtin | fixed | fixed(n) -> fixed | Lift an integer into a Q16.16 fixed-point value. | 50 |
Converts an integer into a fixed value (Ludic's Q16.16 fixed-point type), so it can take part in fractional arithmetic. Ludic has no floating point; fixed is how you carry sub-pixel precision for smooth movement and physics-like accumulation. Use fixed when you need to combine an int with fixed-point values or divide to get a fraction — for example fixed(1) / fixed(4) is 0.25. Convert back to a whole number for drawing with flr.
Parameters:
n— the integer to lift into fixed-point
program SmoothAccumulate {
handler ComputeStep phase Start {
let full_speed = fixed(3)
let half_speed = full_speed / fixed(2)
let two_steps = half_speed + half_speed
print(floor(two_steps))
}
