Re: [Haskell-cafe] Why does [1.0, 3 ..4] contain 5?

Sorry I must be a bit tired :) On 10/19/2016 09:16 PM, Silvio Frischknecht wrote:

Hi,

I don't claim to know the real reason. But I can see that it would make some things more stable or rather it makes the stable versions look nicer.

[1,1.1 .. 2] looks better than [1,1.1 .. 2.05]

If you define it like you suggest

numericEnumFromThenTo e1 e2 e3 = takeWhile (<=e1) [e2, e3 ..] :: [Float] numericEnumFromThenTo e1 e2 e3 = takeWhile (<=e3) [e1, e2 ..] :: [Float]

I get

length $ numericEnumFromThenTo 1 1.1 2 === 10 length $ numericEnumFromThenTo 2 1.2 3 === 11 length $ numericEnumFromThenTo 2 2.1 3 == 11

Cheers, Silvio
