Corrected pseudocode (a should be incremented first)
I flipped the order of the lines: Bsq ← A*A - N // equivalently: Bsq ← Bsq + 2*A + 1 :::and::: A ← A + 1
Line 16:
::Bsq ← A*A - N
::while Bsq isn't a square:
:::Bsq ← A*A - N // equivalently: Bsq ← Bsq + 2*A + 1
:::A ← A + 1
:::Bsq ← A*A - N // equivalently: Bsq ← Bsq + 2*A + 1
::endwhile
::return A - sqrt(Bsq) // or A + sqrt(Bsq)
