No, this is independent and even documented: To get evaluation of input for which gamma is negative and the ceiling is even, we must explicitly make the input complex. This is a known issue, see :trac:`12521`:: sage: log_gamma(-2.1) NaN sage: log_gamma(CC(-2.1)) 1.53171380819509 + 3.14159265358979*I The beta() issue works in 7.3beta4 so where is the problem exactly? -- You received this message because you are subscribed to the Google Groups "sage-devel" group.
