Use these helpers for common math inside strategy expressions.

• abs(x), min(a, b), max(a, b), clamp(x, lo, hi).
• sqrt(x), exp(x), log(x), sin(x), cos(x), tan(x), pow(x, y).
• min/max/clamp require same-typed args after DSL type checks.

Use these helpers whenever you want quantities and prices to scale correctly.

• base(literal): compile-time conversion to base-scaled fixed-point quantity (10^base_scale, default 10^8).
• price(literal): compile-time conversion to price-scaled integer (10^price_scale, default 10^8).
• base_units(i64): converts whole units into base-scaled quantity.
• as_base(expr): cast marker carrying quantity semantics without extra runtime math.

These helpers cover type conversion, randomization helpers, and portfolio lookups.

• int(x), float(x).
• rand_u32(salt).
• rand_ppm(max_ppm, salt).
• portfolio_score_live(asset_id), portfolio_score(asset_id).
• portfolio_rank_desc(asset_id), portfolio_rank_asc(asset_id).

len and indexing stay safe even when a value would normally go out of bounds.

• len(self.<state_array>) and len(self.<extra_buffer>) are supported.
• Negative indexes are translated from end, then clamped into valid bounds.
• Out-of-range indexing saturates to nearest valid element.
• If an Extra buffer is absent/empty, indexed reads return 0/0.0 safely.

These are the arithmetic, comparison, boolean, and bitwise operators you can use in the DSL.

• Arithmetic: +, -, *, /, //, %.
• Bitwise: &, |, ^, ~, <<, >> (i64 operands).
• Shift amounts are clamped to [0, 63] for deterministic behavior.
• Comparisons: <, <=, >, >=, ==, != (including chained comparisons).
• Boolean: and, or, not.
• // and % follow deterministic floor/mod helpers; divide/mod by zero returns 0 in these integer paths.
