I have an array a with 9 components and when i set precision for this array, components of a also get the precision.however, i want to avoid that and only the number get the precision. for instance, a[1,1]+2.000000000000000 and so on. is there anyway i can do that?

a:=Array[a1,{3,3}]+2
SetPrecision[a,16]

Use SetAttributes[a1, NHoldAll] to prevent arguments of a1 from getting numericized. – Carl Woll Jan 30 '18 at 15:10

It helps that I knew to search for NHoldAll. – Carl Woll Jan 30 '18 at 15:18
