-- Option variable: taylor_logexpand Default value: `true`

`taylor_logexpand` controls expansions of logarithms in `taylor` series.

When `taylor_logexpand` is `true`, all logarithms are expanded fully so that zero-recognition problems involving logarithmic identities do not disturb the expansion process. However, this scheme is not always mathematically correct since it ignores branch information.

When `taylor_logexpand` is set to `false`, then the only expansion of logarithms that occur is that necessary to obtain a formal power series.

```(%o1)                                true
(%i2) ```
