Will it? Most of them will not fit
Sure, they will. float has 32 bits, just like int, so it can't
possibly hold a
value larger than an int can hold.
float can't hold more distinct values than int, but a float can
have integer values greater than int.max. (Also, there are int
values that a float cannot store.)
This code passes with flying colors
foreach(i; int.min .. int.max)
assert(cast(float)i == i);
That's because both sides are casted to float.
[...]
float.max isn't an integral value,
It's not a value that an int can store, but it's an integer in
the mathematical sense.
