Implicit conversions between SIMD values can lose data about mojo HOT 3 CLOSED

This appears to be another symptom of the issue described in #2860

from mojo.

I think this is definitely a bug since people trying to cast ints to floats or floats to ints would not reasonably expect their values to first be implicitly cast to bools.

from mojo.

I guess the correct way to change types is to do like this :

def main():
    var y:Int = 1337
    var y0 = Int32(y)
    var y1 = y0.cast[DType.float32]()
    var y2 = y1.cast[DType.uint32]()
    print("y :",y)
    print("y0 :",y0)
    print("y1 :",y1)
    print("y2 :",y2)
    y0 = -1
    y2 = y0.cast[DType.uint32]()
    print("y2 :",y2)

because it seems to give expected answers

y : 1337
y0 : 1337
y1 : 1337.0
y2 : 1337
y2 : 4294967295

so, maybe not a bug but a misunderstanding.

If someone could confirm that's the correct way to do it, I'll be happy close the bug.
