Reinterpret the underlying bits as a signed/unsigned integer

Description

This operation is only allowed for 64-bit integers. For lower bits integers, you can safely use the $cast() operation.

Usage

<Expr>$reinterpret(..., signed = TRUE)

Arguments

…	These dots are for future extensions and must be empty.
signed	If TRUE (default), reinterpret as pl$Int64. Otherwise, reinterpret as pl$UInt64.

Value

A polars expression

Examples

library("polars")

df <- pl$DataFrame(a = c(1, 1, 2))$cast(pl$UInt64)

# Create a Series with 3 nulls, append column a then rechunk
df$with_columns(
  reinterpreted = pl$col("a")$reinterpret()
)
