In int64: 64 bit integer types

Description Objects from the Class Slots Extends Methods Author(s) See Also Examples

Vector of signed 64 bit integers

Objects can be created by using the int64 function, by converting character vectors or integer vectors using the as.int64 function.

.Data:: list of integer vectors of length 2. Each int64 number is coded as two integers.
NAMES:: Used for names of vectors. This is only being used through the names and names<- functions.

Class "list", from data part. Class "vector", by class "list", distance 2.

as.int64 to convert character or integer vectors.

int64 to create new int64 vectors of a given size.

The uint64 class to represent unsigned 64 bit integer vectors.

    x[1:2] <- 1:2

    x * 2L
    x + x
    x - 3L
    
    # arithmetic operations first convert both operands to 64 bit integer type
    # so some precision will be lost
    as.int64(1) + 1.5
