Common math for 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).
• round(x) rounds to the nearest whole number, halves away from zero (0.5 becomes 1, -0.5 becomes -1) — unlike Python's round, which sends halves to the nearest even number.
• min, max, and clamp take arguments of one kind of number.

base(...) and price(...) turn the numbers you write into order sizes and prices.

• Both accept numbers and expressions: price(99.5), price(self.cap), base(computed).
• Numbers you write and float parameters convert exactly. Other computed decimals round to the nearest unit, halves away from zero. A decimal string with too many places is rejected.
• base_units(n) turns a whole number of units into a quantity; as_base(x) re-labels an already-converted value without changing it.

Type conversion, reproducible randomness, cross-asset lookups.

• int(x), float(x).
• rand_u32(salt) — a reproducible pseudo-random 32-bit whole number.
• rand_ppm(max_ppm, salt) — a reproducible value in parts per million (1,000,000 = 100%).
• portfolio_score_live(asset_id), portfolio_score(asset_id).
• portfolio_rank_desc(asset_id), portfolio_rank_asc(asset_id).

len and indexing stay safe at the edges.

• len(self.<state_array>) and len(self.<extra_buffer>) are supported.
• Negative indexes count from the end, then snap into valid bounds.
• Out-of-range indexes snap to the nearest valid element.
• A missing or empty Extra buffer reads as 0 (or 0.0).

Arithmetic, comparison, boolean, and bitwise operators.

• Arithmetic: +, -, *, /, //, %.
• Bitwise: &, |, ^, ~, <<, >> (whole-number operands). Shift amounts are clamped to [0, 63].
• Comparisons: <, <=, >, >=, ==, !=, including chained comparisons like lo < x < hi.
• Boolean: and, or, not.
• // and % are exact; dividing or taking a remainder by zero returns 0.
