VARIANT2_INTEGER_MATH_SQRT_FIXUP checks that "r" is an integer part of "sqrt(2^64 + sqrt_input) * 2 - 2^33" and adds or subtracts 1 if needed
It's hard to understand how it works, so here is a full calculation of formulas used in VARIANT2_INTEGER_MATH_SQRT_FIXUP
The following inequalities must hold for r if it's an integer part of "sqrt(2^64 + sqrt_input) * 2 - 2^33":
1) r <= sqrt(2^64 + sqrt_input) * 2 - 2^33
2) r + 1 > sqrt(2^64 + sqrt_input) * 2 - 2^33
We need to check them using only unsigned integer arithmetic to avoid rounding errors and undefined behavior
First inequality: r <= sqrt(2^64 + sqrt_input) * 2 - 2^33
-----------------------------------------------------------------------------------
r <= sqrt(2^64 + sqrt_input) * 2 - 2^33
r + 2^33 <= sqrt(2^64 + sqrt_input) * 2
r/2 + 2^32 <= sqrt(2^64 + sqrt_input)
(r/2 + 2^32)^2 <= 2^64 + sqrt_input
Rewrite r as r = s * 2 + b (s = trunc(r/2), b is 0 or 1)
((s*2+b)/2 + 2^32)^2 <= 2^64 + sqrt_input
(s*2+b)^2/4 + 2*2^32*(s*2+b)/2 + 2^64 <= 2^64 + sqrt_input
(s*2+b)^2/4 + 2*2^32*(s*2+b)/2 <= sqrt_input
(s*2+b)^2/4 + 2^32*r <= sqrt_input
(s^2*4+2*s*2*b+b^2)/4 + 2^32*r <= sqrt_input
s^2+s*b+b^2/4 + 2^32*r <= sqrt_input
s*(s+b) + b^2/4 + 2^32*r <= sqrt_input
Let r2 = s*(s+b) + r*2^32
r2 + b^2/4 <= sqrt_input
If this inequality doesn't hold, then we must decrement r: IF "r2 + b^2/4 > sqrt_input" THEN r = r - 1
b can be 0 or 1
If b is 0 then we need to compare "r2 > sqrt_input"
If b is 1 then b^2/4 = 0.25, so we need to compare "r2 + 0.25 > sqrt_input"
Since both r2 and sqrt_input are integers, we can safely replace it with "r2 + 1 > sqrt_input"
-----------------------------------------------------------------------------------
Both cases can be merged to a single expression "r2 + b > sqrt_input"
-----------------------------------------------------------------------------------
There will be no overflow when calculating "r2 + b", so it's safe to compare with sqrt_input:
r2 + b = s*(s+b) + r*2^32 + b
The largest value s, b and r can have is s = 1779033703, b = 1, r = 3558067407 when sqrt_input = 2^64 - 1
r2 + b <= 1779033703*1779033704 + 3558067407*2^32 + 1 = 18446744068217447385 < 2^64
Second inequality: r + 1 > sqrt(2^64 + sqrt_input) * 2 - 2^33
-----------------------------------------------------------------------------------
r + 1 > sqrt(2^64 + sqrt_input) * 2 - 2^33
r + 1 + 2^33 > sqrt(2^64 + sqrt_input) * 2
((r+1)/2 + 2^32)^2 > 2^64 + sqrt_input
Rewrite r as r = s * 2 + b (s = trunc(r/2), b is 0 or 1)
((s*2+b+1)/2 + 2^32)^2 > 2^64 + sqrt_input
(s*2+b+1)^2/4 + 2*(s*2+b+1)/2*2^32 + 2^64 > 2^64 + sqrt_input
(s*2+b+1)^2/4 + (s*2+b+1)*2^32 > sqrt_input
(s*2+b+1)^2/4 + (r+1)*2^32 > sqrt_input
(s*2+(b+1))^2/4 + r*2^32 + 2^32 > sqrt_input
(s^2*4+2*s*2*(b+1)+(b+1)^2)/4 + r*2^32 + 2^32 > sqrt_input
s^2+s*(b+1)+(b+1)^2/4 + r*2^32 + 2^32 > sqrt_input
s*(s+b) + s + (b+1)^2/4 + r*2^32 + 2^32 > sqrt_input
Let r2 = s*(s+b) + r*2^32
r2 + s + (b+1)^2/4 + 2^32 > sqrt_input
r2 + 2^32 + (b+1)^2/4 > sqrt_input - s
If this inequality doesn't hold, then we must decrement r: IF "r2 + 2^32 + (b+1)^2/4 <= sqrt_input - s" THEN r = r - 1
b can be 0 or 1
If b is 0 then we need to compare "r2 + 2^32 + 1/4 <= sqrt_input - s" which is equal to "r2 + 2^32 < sqrt_input - s" because all numbers here are integers
If b is 1 then (b+1)^2/4 = 1, so we need to compare "r2 + 2^32 + 1 <= sqrt_input - s" which is also equal to "r2 + 2^32 < sqrt_input - s"
-----------------------------------------------------------------------------------
Both cases can be merged to a single expression "r2 + 2^32 < sqrt_input - s"
-----------------------------------------------------------------------------------
There will be no overflow when calculating "r2 + 2^32":
r2 + 2^32 = s*(s+b) + r*2^32 + 2^32 = s*(s+b) + (r+1)*2^32
The largest value s, b and r can have is s = 1779033703, b = 1, r = 3558067407 when sqrt_input = 2^64 - 1
r2 + b <= 1779033703*1779033704 + 3558067408*2^32 = 18446744072512414680 < 2^64
There will be no integer overflow when calculating "sqrt_input - s", i.e. "sqrt_input >= s" at all times:
s = trunc(r/2) = trunc(sqrt(2^64 + sqrt_input) - 2^32) < sqrt(2^64 + sqrt_input) - 2^32 + 1
sqrt_input > sqrt(2^64 + sqrt_input) - 2^32 + 1
sqrt_input + 2^32 - 1 > sqrt(2^64 + sqrt_input)
(sqrt_input + 2^32 - 1)^2 > sqrt_input + 2^64
sqrt_input^2 + 2*sqrt_input*(2^32 - 1) + (2^32-1)^2 > sqrt_input + 2^64
sqrt_input^2 + sqrt_input*(2^33 - 2) + (2^32-1)^2 > sqrt_input + 2^64
sqrt_input^2 + sqrt_input*(2^33 - 3) + (2^32-1)^2 > 2^64
sqrt_input^2 + sqrt_input*(2^33 - 3) + 2^64-2^33+1 > 2^64
sqrt_input^2 + sqrt_input*(2^33 - 3) - 2^33 + 1 > 0
This inequality is true if sqrt_input > 1 and it's easy to check that s = 0 if sqrt_input is 0 or 1, so there will be no integer overflow
