    Description

      Hi,

      I found that the INTEGER overflow occurs in JSON related functions without any warning:

      SELECT JSON_VALID('1e9999999999999999999999'); -- 1
      		 
      SELECT JSON_NORMALIZE('1e9999999999999999999999'); -- 1.0E9223372036854775807
      		 
      SELECT JSON_NORMALIZE('1e8888888888888888888888'); -- 1.0E9223372036854775807
      		 
      SELECT JSON_EQUALS('1e9999999999999999999999','1e8888888888888888888888'); -- 1
      		 
      SHOW WARNINGS; -- empty
