Problem: Trying to array 25,000 trees along a highway. Error: "Please enter an integer from 1 to 20000" when typing 25000 . Solution: Used two arrays: 12,500 trees × 2, stacked.
A: Because an integer is a whole number. An array with 1.5 items is geometrically impossible. Use rounding or use the MEASURE command instead of DIVIDE if you need fractional spacing.
