FEATURE REQUEST: Add a "roughly" operator

[janetacarr]

It might be useful to have an operator that says something is roughly like something else:

3.14 === ~3 ;; true
3 === ~3.14 ;; true
2 + 2 == ~5 ;; true for large values of two

The precise definition of roughly should depend an a Quantum Random Number Generator so the universe can decide whether or not this is truly roughly equal to the other operand.

Don't forget that 3.14 ~ 3 should be the same as 3.14 = ~3 and 2 + 2 ~~ 5 the same as 2 + 2 == ~5.
Also don't forget that ~ 3.14 3 should be the same as ~3.14 = 3 and different from 3.14 ~ 3

I think we already have something like that.

If you want to be much less precise, you can use =.

3 = 3.14! //true

3 = 3.14! //true

It's a less precise equal not a roughly equal
exemples:

print 3 = 3 ! // true
print 3 ~ 3 ! // false because roughly is not equal

if 3 = 3.14 {
print 3.1 ! // 3.1
print 3 ! // 3.14
}
if 3 ~ 3.14 {
print 3.1 ! // 3.14
print 3 ! // 3
}

I don't understand what you mean here.

if 3 = 3.14 {
print 3.1 ! // 3.1
print 3 ! // 3.14
}
if 3 ~ 3.14 {
print 3.1 ! // 3.14
print 3 ! // 3
}

Why does 3 = 3.14 makes it so that print 3 prints '3.14'?
Why does 3 ~ 3.14 makes it so that print 3.1 prints '3.14'?

Also if you want to do print 3 ~ 3 ! // false, just do 3 = 3 && 3 ;= 3 and you get the same thing.

[guigui0246]

Also if you want to do print 3 ~ 3 ! // false, just do 3 = 3 && 3 ;= 3 and you get the same thing.

const const n = 3!
print 3 ~ n ! //false
print 3 = n && 3 ;= n ! // false
const const n = 3.1!
print 3 ~ n ! //true
print 3 = n && 3 ;= n ! // false

About the other I was wrong for the second if (it's how it would work for ~ 3 = 3.14)

3 = 3.14 ! // Now the variable 3 is set to 3.14 so `print 3` prints `3.14`
3 ~ 3.14 ! // Now the variable 3 is roughly set to 3.14 so `print 3` prints a number close to 3.14 (like `3.1` or `3.1654`) 
~ 3 = 3.14! // Now the variables of value around 3 (like `3.1` or `2.98`) are set to 3.14 so `print 3.1` prints `3.14`
~ 2 ~ 3.14! // Now the variables of value around 3 (like `3.1` or `2.98`) are roughly set to 3.14 so `print 2.98` could print `3.1654`

Are you proposing something that is both a comparator and an assignment at the same time?
