Integers beyond what a double holds exactly

TOML integers are 64-bit. Those beyond 2^53 cannot be held exactly by a double, so toml_parse() returns them, by default, as a toml_bigint vector: their exact decimal text, with a class.

Usage

toml_bigint(x)

Arguments

x

Decimal strings ("-9223372036854775808"), or whole numbers within 2^53. NA is kept.

Value

A character vector of class toml_bigint, holding canonical decimal text: no leading zeros or plus sign.

Examples

x <- toml_bigint(c("9007199254740993", "-42"))
x
#> <toml_bigint[2]>
#> [1] 9007199254740993 -42             
as.numeric(x)   # loses the precision a bigint keeps
#> [1]  9.007199e+15 -4.200000e+01
toml_parse("big = 9223372036854775807")$big
#> <toml_bigint[1]>
#> [1] 9223372036854775807
