ti.append only support i32.

[FantasyVR]

Concisely describe the proposed feature

The user in the forum wants to use ti.append with float data type. Forum link

However, Taichi doesn't support that according to here.

Should we support more data types?

[k-ye]

+1. Let's support f32 as a start :-)

[FantasyVR]

@k-ye Do you have some ideas about how to implement this feature?

Now, a hack solution is that I could simply change the signature of function Dynamic_append:

taichi/taichi/runtime/llvm/node_dynamic.h

Line 61 in 3b179fb

i32 Dynamic_append(Ptr meta_, Ptr node_, i32 data) {

as

i32 Dynamic_append(Ptr meta_, Ptr node_, f32 data) {

It seems like we need to wrap the above function signature with a template to allow it?

[k-ye]

Templatizing this SGTM! Feel free to take this over, you likely need to spend some time dealing with template functions in LLVM :-) @WenheLI

Hi @WenheLI, sorry to bother you. Is there any progress on this issue?

[WenheLI]

Still looking into the solution. Will keep you posted once find anything!
Sorry for the late reply!
