Incorrectly treating decimals as integer types

[sunyinqi0508]

Describe the bug
MonetDBe will treat float literals as integers in simple queries like SELECT 3.14;

To Reproduce
Steps to reproduce the behavior:
In python:

from monetdbe import connect
c = connect()
c.execute("select 3.14;").fetchdf()

Expected behavior
It should print 3.14 instead of 314

Screenshots

Software versions

• OS and version: macOS 12.5
• Python version: 3.6
• MonetDBe-Python version: 0.10.1

Additional context
This problem also happen in the c version of monetdbe (as shown in the second screenshot). But in the full version of MonetDB don't seem to have this issue.

Interesting find. I'm not entirely sure how to read the second screenshot but the first is very clear.
Note that in these examples, 3.14 is a decimal, not a floating point number. The following query shows the same behavior, it returns 4200: select cast(42 as decimal(5,2)).
