Different error code from MySQL when inserting incorrect bigint value

Description

Bug Report

1. Minimal reproduce step (Required)

drop table if exists t0;create table t0 (col0 VARCHAR(0), col1 TINYINT, col2 TEXT, col3 BLOB, col4 BIGINT);insert into t0 values (NULL, '-128', 't', 'b', '2 ^ 63 - 1');

2. What did you expect to see? (Required)

From both errors it is clear I shouldn't use 2^63 in the value. But I'm confused with the meaning of the error.
