Haste does not work correctly due to rounding

Having Haste 2 doesn't make you cut logs faster. (Only tried with an Efficiency 5 diamond axe)

(I know this is a duplicate of MC-25330, but it's still the case in 1.13...)

 

Here is some testing I have done (done in 1.13.1-pre2 by mining a 10*9 area, see picture for more details) :

-------------------------------------------------------------------------------------

Diamond Axe with Efficiency V on Oak Logs : 715 (time to mine the 90 blocks in ticks)

Diam Axe Effi V with Haste II on Oak Logs : 716

Diam Axe Effi V with Mining Fatigue II on Oak Logs :  2314

-------------------------------------------------------------------------------------

Diamond Axe on Oak Logs : 1246

Diam Axe with Haste II on Oak Logs : 1068

-------------------------------------------------------------------------------------

So the Haste effect seems to work on axes with low efficiency value, but doesn't seems to work on axes with high efficiency value...

I did try this on Oak Planks as well and I got the same results.

I wanted to compare with something, here are the results :

-------------------------------------------------------------------------------------

Diamond Pickaxe with Efficiency V on Stone : 711

Diam Pick Effi V with Haste II on Stone : 150

-------------------------------------------------------------------------------------

So yeah, there is definitively somthingwrong with Axes...

 

 

Addendum :

During my testing I found something else, I let you see :

-------------------------------------------------------------------------------------

STONE Axe with Efficiency V on Oak Logs : 711

STONE Axe Effi V with Haste II on Oak Logs : 714

-------------------------------------------------------------------------------------

A Stone Axe with Efficiency V is as fast as Diamond Axe with the same enchantment... (Note : That isn't the case with Wooden Axe that takes about 820 ticks)...
