Perhaps you assigned a value to pi. Try removing the pi variable.

```
pi
[1] 3.141593
pi <- 2
pi
[1] 2
rm(pi)

[1] 3.141593
```

Do you restore .RData at startup? You can check this out at Tools -> Global Options and look in the workspace section. I recommend not restoring it at startup and never saving workspace on exit.

Check that nothing is saved in your R.

```
#install.packages("usethis") # you may need to run this if it isn't installed
usethis::edit_r_profile()
```

hello,

I just unchecked it. The pi value looks correct now. Thanks.
