Subject: Altimeter: fix output format for hPa/InHg settings
X-Git-Url: https://git.mxchange.org/?a=commitdiff_plain;h=84a26de9ae9ade8629dee53cac8b9357f0930690;p=flightgear.git

Altimeter: fix output format for hPa/InHg settings

Usually, in a real cockpit, altimeter shows hPa setting as an integer number and InHg setting is limited to 2 decimals

In aviation we don't need higher numeric precision
