what is R equivalent of Fortran DOUBLE PRECISION ?
...symbol in " c14 <- as.double( 7.785205408500864D"
The above "D" is used in Fortran language to indicate the memory starage mode. That is for instructing Fortran compiler
to store such a REAL constant in DOUBLE PRECISION... am I right ?
Since R cannot undestand numerical conatant post-fixed by the letter "D", I wonder how I can instruct R interpreter to
store such a numerical constant reserving as muh memory as necessary so as to accommodate a double precision number.
I noticed R accepts the folllowing syntax but I do not know if i have achieved my goal thsi way...
