Thanks, @aman-095. This looks good apart from the realf and imagf usage. Once resolved, this should be ready for merge.

@aman-095 Are you planning on adding the C and Fortran implementations in a follow-up PR? Or will you be adding them to this PR?

[aman-095]

@kgryte I'll correct the implementation and yes I will add the C and Fortran implementation in this PR itself.
