listOf(1,2,3).sumOf { it.toDouble() } //works fine
listOf(1,2,3).sumOf { it.toFloat() } //error: no applicable overload

can someone explain why?

Considering that workaround exists, we decided that overloads for Float do not pull their weight

wtf, it's literally 1 function with a 5loc body that is missing, how is that too much to ask for

but thanks for the link

@LastExceed not one, but something about 12-13, considering all collection-like containers.

ok fair, i didnt consider that. but still, it seems pretty trivial to implement, and i find it bizarre that UInt or even BigInteger is apparently more important than Float

[ephemient]

like Byte and Short, `Float`'s use should usually be limited to storage, not computation. even Android has dropped FloatMath since Math on Double is faster.

oh thats interesting, i didn't know that. in that case the decision makes sense to me, ty 4 explaining
