  Hi there, i'm a new user of Nimrod. This simple code doesn't work:

  let

  x = 1 z = 4'u16

  echo(x * z )

  the compiler complains: Error: type mismatch: got (int, uint16)

  Is it impossible mixing ints and uints?

  Then, another question: echo(7/3 ) gives: 2.3333333333333335e+000

  how can i get: 2.333333 with the precision i want?

  Thx - Regards.

  It is possible to mix different types if you cast one to another:

  
  echo(x * int(z))
  Run

  To format floats you can use the formatFloat proc from the strutils module:

  
  import strutils
  echo(formatFloat(7/3, ffDecimal, 6))
  Run

  Some people like to create their own template/inline alias to shorten that (ff or something like that) to avoid having to pass the same arguments over and over.
