yeah the synthetic division is much simpler, idek where you could've possibly got those values in the long division from

caesar #3471

yay! c: bzzzzzzzzzt

caesar #3469

of course! it's all explained on the Wikipedia page for synthetic division

hopefully apioforum uses markdown so that link works

caesar #3466

divide 3x³ + 2x² + 4x + 7 by x² + 7x - 2 using long division (hard, extremely complicated. borderline impossible. useless)

do the same division using synthetic division (easy, not at all inconvenient, extremely simple. useful) (i also like useful)

caesar #3463

long polynomial division is extremely complicated, i'd say it's more opaque for that reason

caesar #3456

indeed! bn + d

oh cool, this is related to synthetic division (the best kind of polynomial division). but i discovered this algorithm myself

caesar (edited ) #3447

there's a faster algorithm

start with n = 1

if it's all zeroes the number is 0

ignore all digits up to and including the first 1 (left-to-right)

when you see a zero, 2n

when you see a one, 2n + 1

so 00000101:

n = 1 (1)01

n = 2 1(0)1

n = 4 + 1 10(1)

n = 5
