383 :: Floating point division

  I have two 64 bit integers, and I want to divide these two integers using floating point division instead of integer division. I assume the way to do it is to convert both to 64 bit floats. How do I do this in Nimrod?

  var
    x: int64 = 10
    y: int64 = 3
  
  echo float64(x)/float64(y)
  Run

  see http://nimrod-lang.org/manual.html#type-conversions

  Or you can use the toFloat procedure in system.nim

  @micklat: Thanks, that works.

  @Varriount: Does toFloat work with int64? I get this error:

  Error: type mismatch: got (int64) but expected one of: system.toFloat(i: int): float

  One more thing. When I print a float with echo, it prints in scientific notation. Can I print it as is, without scientific notation?

  import StrUtils var a: int64 = 10 b: int64 = 3 echo formatFloat(a.float64 / b.float64, FFDecimal, 2) # prints '3.33'

  Run
