I agree entirely. Once you have floating point, you should have the standard functions that the vast majority of programming languages that support floating point arithmetic have. Vim now has essentially all of the functionality of grep and sed built in. Adding the standard math library would give Vim most of the functionality of awk that is currently missing in Vim.
