History using REAL32 does not appear to write properly

[cacraigucar]

What happened?

When I was outputting history fields using REAL32, the values written to the history file are incorrect. Simply switching the output to hist_precision;h1: REAL64 solved the problem

What are the steps to reproduce the bug?

Use hist_precision;h1: REAL32 instead of hist_precision;h1: REAL64

I used my own branch but same result with the head of CAM-SIMA (as of 12/14/2024)
