Is there (or how could one write) a function that gives me this vector [0, 1//2, 1, 3//2, 2] from this vector [0//2, 1//2, 2//2, 3//2, 4//2]?

ha, in the end both of us edited the answers to fit the cases. The OP can now choose the answer in their preferred style.

Hi Henrique, your code is much more elegant, and I learned from it. Cheers.

If you want to learn more about this style, this is basically a extreme application of the Bouncer Pattern . Most articles define it as “make all validations first and then deal with the happy path”, but I use it more generally as “if it is easy to check for and deal with a corner case, do this in th…

The origin of the question stems from the fact that I was unable to populate a vector with the values [0,1 // 2,1,3 // 2,2] by hand because julia automatically transformed them all into rationals. I just wanted to see how the plot with the “better formatted” ticks looked like. But then my problem …

[image] DNF: Seems like a classic XY-problem. in fact it is a problem on the X axis (on the Y axis there are only float(real) numbers). Seriously, you are right to say that I tried to solve a problem (X) in the wrong way and so I self-generated a new problem (Y), which became the problem I p…

[image] Henrique_Becker: but there’s nothing in the language that suggests that Julia will try to do an automatic conversion in this situation. NB: this behavior is covered in the manual: Integers mixed with rationals are promoted to rationals

Yes, I am quite familiar with mathematical questions. But naively I thought that in julia it was done differently and I tried to do something like you suggest. But I tried with a monster like Vector {Union {Rational, Int}}[ ] that julia didn’t digest :laughing:

[image] Henrique_Becker: What I find a little strange that Int is not a subtype of Rational . Fyi, there is this past post from the boss that might still be valid.

[image] rocco_sprmnt21: Vector {Union {Rational, Int}}[ ] You were near! @show Union{Real,Int}[0, 1//2, 1, 3//2, 4//2] @show Union{Rational,Int}[0, 1//2, 1, 3//2, 4//2] yields Union{Real, Int}[0, 1 // 2, 1, 3 // 2, 4 // 2] = Real[0, 1//2, 1, 3//2, 2//1] Union{Rational, Int}[0, 1 // 2, 1, 3…
