nimforum mirror - These Rosetta Code examples don't compile with 0.17.0

I'm really new to Nim and started playing around with 0.17.0 on Linux.

I went to Rosetta Code: https://rosettacode.org/wiki/Category:Nim to get code examples to run.

The following code examples wouldn't compile with: $ nim -d:release c <file.nim>

montecarlo.nim


import math
randomize()

proc pi(nthrows): float =
  var inside = 0
  for i in 1..int64(nthrows):
    if hypot(random(1.0), random(1.0)) < 1:
      inc inside
  return float(4 * inside) / nthrows

for n in [10e4, 10e6, 10e7, 10e8]:
  echo pi(n)

rootsofunity.nim


import complex, math

proc rect(r, phi: float): Complex = (r * cos(phi), sin(phi))

proc croots(n): seq[Complex] =
  result = @[]
  if n <= 0: return
  for k in 0 .. < n:
    result.add rect(1, 2 * k.float * Pi / n.float)

for nr in 2..10:
  echo nr, " ", croots(nr)

How do you make these examples work with 0.17?
