isInsufficientSentinel()

function isInsufficientSentinel(basisPoints): boolean;

Whether basisPoints is the UINT16_MAX_BASIS_POINTS marker rather than a real percentage.

Parameters

Parameter	Type	Description
basisPoints	number	A collateral-factor or uncapped risk-factor value in basis points.

Returns

boolean

true when the value is the sentinel marker and must not be displayed as a number.

Remarks

Only meaningful for uncapped results — a calculateCollateralFactorBasisPoints return value, or a calculateRiskFactorBasisPoints call with maxOneHundredPercent: false.

Even there it is not a complete test of an uncapped risk factor. Only the zero-liquidation-factor exit returns this value verbatim. When the collateral value floors to zero instead, calculateCollateralFactorBasisPoints returns the sentinel and calculateRiskFactorBasisPoints then divides it by the liquidation factor, yielding floor(65535 * 10000 / liquidationFactor) — 81918 at a liquidation factor of 8000, which this predicate does not match. The two coincide only when the liquidation factor is exactly 10000. For an uncapped value, treat anything at or above 10000 as insufficient rather than relying on this predicate alone. The default capped path (every SDK React hook) never produces this raw value; see UINT16_MAX_BASIS_POINTS for how to gate a capped result instead.
