When I run the select statement, I am getting different data…

I suggest you use the native "psql"-client and chech the results from that first.
 
Specifically this behavior can be readily observed using the following query:
 
SELECT '1.234567+e06'::float4::numeric;
 
Wow, that really surprices me!
 
SELECT '1234567'::float4::numeric;
┌─────────┐
│ numeric │
├─────────┤
│ 1234570 │
└─────────┘
(1 row)

How can this be sane?
