Functions

External & Public

computeHalfBessel

computeHalfBesselfunction

function computeHalfBessel(uint256 order, int256 x) public pure returns (int256 result)

A callable deployment has not been resolved for this reference.

• Visibility: public
• State Mutability: pure
• Parameters: uint256 order, int256 x
• Returns: int256 result
• NatSpec: Computes J_{order + 1/2}(x) using a 4-term Taylor series expansion.
