Float64 ICM and stack vectors

Several tournament and stack helpers accept F64VectorInput: number[] or Float64Array.

Default unchanged

If you omit returnFormat, you get number[] in and number[] out.

Float64 output​

Pass 'float64' as the last argument (or returnFormat where documented) to receive a Float64Array:

const stacks = new Float64Array([12000, 9000, 6000, 3000]);

const pWin = poker.icmWinProbabilitiesHarville(stacks, 'float64');
const ev = poker.icmExpectedPayouts(stacks, payoutsF64, 'float64');

const placement = poker.icmHarvillePlacementProbabilities(stacks, 'float64');
// flat n×n row-major when returnFormat is float64
