- Preconditions:
- |h| bounded by 1.1*2^26,1.1*2^25,1.1*2^26,1.1*2^25,etc.
-
- Write p=2^255-19; q=floor(h/p).
- Basic claim: q = floor(2^(-255)(h + 19 2^(-25)h9 + 2^(-1))).
-
- Proof:
- Have |h|<=p so |q|<=1 so |19^2 2^(-255) q|<1/4.
- Also have |h-2^230 h9|<2^231 so |19 2^(-255)(h-2^230 h9)|<1/4.
-
- Write y=2^(-1)-19^2 2^(-255)q-19 2^(-255)(h-2^230 h9).
- Then 0<y<1.
-
- Write r=h-pq.
- Have 0<=r<=p-1=2^255-20.
- Thus 0<=r+19(2^-255)r<r+19(2^-255)2^255<=2^255-1.
-
- Write x=r+19(2^-255)r+y.
- Then 0<x<2^255 so floor(2^(-255)x) = 0 so floor(q+2^(-255)x) = q.
-
- Have q+2^(-255)x = 2^(-255)(h + 19 2^(-25) h9 + 2^(-1))
- so floor(2^(-255)(h + 19 2^(-25) h9 + 2^(-1))) = q.
