Research direction

Start by inspecting the existing logabsgamma(::Real) implementation in src/gamma.jl, around the line referenced in the error. Use the Julia REPL example with 1+im to verify that the complex call is supported without the reported MethodError.

Written by the indexing model from the issue text.

Description

This was a bit surprising:

julia> logabsgamma(1+im)
ERROR: MethodError: no method matching logabsgamma(::Complex{Int64})
Closest candidates are:
  logabsgamma(::Real) at ~/.julia/packages/SpecialFunctions/gXPNz/src/gamma.jl:599
