Yes, we can interpret trailing zeros to the left of the decimal point as not 
significant, unless the tolerance is specified explicitly with the ± symbol 
That is standard practice in science and engineering. For example, //Land 
Surveyor Reference Manual// 2nd ed. by Andrew Harbin p. 108 states:

"A zero is //not// significant if it occurs at the end of a measured number 
unless information is available which indicates that it is."

Some people may be ignorant of this convention, but by default we should adopt 
the greatest reasonable uncertainty.
