The use of zero when recording data.
The use of zero when recording data.
(OP)
My colleague and I were having a bit of a back and forth on the use of a Zero in front of a decimal.
Lets say your print callout is .324"+.005" and your measurement is .326". Are both .326" and 0.326" acceptable when recording results?

Although mistaking a comma for digital grouping when it's meant as a decimal point is much more of an issue.

It is a capital mistake to theorise before one has data. Insensibly one begins to twist facts to suit theories, instead of theories to suit facts. (Sherlock Holmes - A Scandal in Bohemia.)

For metric you have the leading zero, inch dimensions do not have the leading zero.
However, you're talking about recording inspection results not preparing a drawing.
I would tend to match the drawing but can't say if that's explicitly correct.
ANSI B4.4M-1981 Inspection of Workpieces (or newer equivalent) may clarify if you work to that.
Given that the OP's units are clearly inches I'm not sure why anyone pointed him to metric specs.

General numbers were always hand-written as a whole number followed by a decimal point + a .0 [point-zero] or significant decimal inch digits, followed by a graphical unit indication, EX: 25.0-in# or 25.033-in, etc.
If the general number was less than one, he always preceded the decimal with a 0. [zero-point], followed by significant decimal digits, followed by a graphical unit indication, EX: 0.50-gal or 0.993-#, etc.
NOTE. JT's only exceptions to this rule were...
(1) 'quantity'. JT specified whole quantity numbers in [brackets]... or on rare occasions, the whole number was followed by a '-ea', EX: [33] [12] or 33-ea or 12-ea
(2) 'sequence'. JT specified whole numbers separated by commas, IE: ... 41, 42, 43 ...
Here where JT's hand writing became a 'signature writing style'... unmistakeably his!
When he has writing general sentences/paragraph 'prose' [for lack of a better term], he always concluded EACH sentence with a tiny( x ) [subscript x], EX...
Recommended max gross weight ground operations at 2200-# x Taxi speed shall be limited to 15-MPH (fast run) x Turning speed shall be limited to 5-mph (fast walk) x All braking must be done without any turn rate (straight ahead) x Inflate tires to maximum recommended pressure +10-PSI x

I have done the same thing with the replacement of 'full stop' with an 'x' and seen others do it for similar reasons, I assume. I did it when working in an environment where I knew my notes or handwriting would be photocopied, possibly repeatably. A simple "dot" can very easily be lost during photocopying, and depending on the writing instrument, can possibly not show up on the original very well. Make an 'x' would force a bolder full stop, and would force even the worst of ink pens and pencils to leave their mark, rather than a simple "dotting" action. I've seen some make a very small circle. Maybe it ties in with whichever preference the person has when playing tic-tac-toe. :)
