split

split(a: number): number[]

Defined in basic/split.ts:21

Returns the result of splitting a double into 2 26-bit doubles.

Theorem 17 (Veltkamp-Dekker): Let a be a p-bit floating-point number, where p >= 3. Choose a splitting point s such that p/2 <= s <= p-1. Then the following algorithm will produce a (p-s)-bit value a_hi and a nonoverlapping (s-1)-bit value a_lo such that abs(a_hi) >= abs(a_lo) and a = a_hi + a_lo.

see e.g. Shewchuk

Parameters:

Name	Type	Description
a	number	A double floating point number

Returns: number[]
