From 0657181167467ec5cfb5a28aacf47ca02f5f4588 Mon Sep 17 00:00:00 2001 From: Alexander Korotkov Date: Sat, 11 Jul 2020 03:20:46 +0300 Subject: Improve error reporting for jsonpath .double() method When jsonpath .double() method detects that numeric or string can't be converted to double precision, it throws an error. This commit makes these errors explicitly express the reason of failure.
