converting string to float

Hello everybody,

I have following string type and try to convert it to float:

a<-"20020104.123456"
str(as.numeric(a))

num 20020104

str(as.real(a))

num 20020104

str(as.double(a))

num 20020104

How can I get an float instead of an integer? How can I set the desired precision?

Thanks in advance
