2746 :: No way to run my code, idk how to force a float as an Int

  hi guys I have this few line,

   nombreDePyramides = 4
  var maxLignes: int = ((nombreDePyramides+2)*(nombreDePyramides+3)/2-4)
  Run

  here the second line is giving me a float but I need a int because of the rest of the code and I can't find the syntax ...

  -Pro-de-Pablo:sastentua pablocolson$ nim c satstentua.nim
  Hint: used config file '/Users/pablocolson/nim/config/nim.cfg' [Conf]
  Hint: system [Processing]
  Hint: satstentua [Processing]
  satstentua.nim(2, 68) Error: type mismatch: got (float) but expected 'int'
  MacBook-Pro-de-Pablo:sastentua pablocolson$
  Run

  thanks for awnsers

  This happens because / on ints returns a float. You want to use div instead, which is integer division.

  var maxLignes = ((nombreDePyramides + 2) * (nombreDePyramides + 3)) div 2 - 4
  Run

  Or, alternatively, convert it – this is clearly the inferior solution, but given here for completeness:

  var maxLignes = int((nombreDePyramides+2)*(nombreDePyramides+3)/2-4)
  Run

  In both cases, you do not need to give the type because it is derived from the expression.
