Detect character input that would overflow signed 64-bit integers

Returns TRUE for any element of x that does not fit in a signed 64-bit integer, papering over a behaviour change across bit64 versions.

Usage

int64_overflows(x)

Arguments

x

A character vector of integer-shaped strings.

Value

A logical vector the same length as x.

Details

bit64 < 4.8.0 silently clamped overflowing character input to the maximum int64; >= 4.8.0 returns NA with a warning. This helper detects both signatures so callers get a consistent logical vector regardless of the installed bit64.

Examples

int64_overflows(c("123", "9223372036854775807", "9223372036854775808"))
#> [1] FALSE FALSE  TRUE
