Hi Charles,
Probably for the same reason it doesn't have short int, short unsigned
int, long int, long unsigned int, long long int, long long unsigned int,
long double etc... There are many built-in types in C and, in order
to keep things simple, I guess the line had to be drew somewhere.
Said otherwise, I don't think the atomic types in R were ever meant to
reflect exactly what's available in C.
Note that some CRAN packages (e.g. bit64) try to remedy this by
providing support for atomic-like types that are not natively supported
by R. I don't know if there is one for float though.
Cheers,
H.

This is strictly a curiosity question. I am aware the R doesn't possess a
float data type. I also don't mean to request that such functionality be
implemented as I'm sure it would require a large amount of work with
potential back compatibility conflicts. But I wanted to know why R has
never had a float data type available?
Regards,
Charles
