ddAddDouble
ddAddDouble(x: number[], y: number): number[]
Defined in double-mixed-double-double/dd-add-double.ts:14
Returns the result of adding a double to a double-double precision floating point number.
- relative error bound: 2u^2, i.e. fl(a+b) = (a+b)(1+ϵ), where ϵ <= 2u^2, u = 0.5 * Number.EPSILON
- the error bound is sharp
