An array variable is associated with a .length property that returns the length of the associated one-dimensional array as a positive int; for example, name1.length returns 4.

Like one-dimensional array variables, a two-dimensional array variable is associated with a .length property, which returns the length of the row array. For example, temperatures1.length returns 2.

The following example creates an array that contains ten variables- five temperature measures (t1 through t5) ... applies the ROUND function to all the variables in one row. For each iteration of the ...
