real {base} | R Documentation |
real
creates a double precision vector of the specified
length. Each element of the vector is equal to 0
.
as.real
attempts to coerce its argument to be of double type.
is.real
returns TRUE
or FALSE
depending on
whether its argument is of double type or not.
real(length = 0) as.real(x, ...) is.real(x)
length |
desired length. |
x |

R has no single precision data type.
All real numbers are stored in double precision format.
These functions are the same as their double
equivalents.
