We can use v x to build a vector of integers. This needs to be adjusted to get the range of integers we desire. Mapping ‘-’ across the vector will accomplish this, although it turns out the plain ‘-’ key will work just as well.
2: 2 2: 2
1: [1, 2, 3, 4, 5, 6, 7, 8, 9] 1: [-4, -3, -2, -1, 0, 1, 2, 3, 4]

2 v x 9 RET 5 V M - or 5 -
Now we use V M ^ to map the exponentiation operator across the vector.
1: [0.0625, 0.125, 0.25, 0.5, 1, 2, 4, 8, 16] . V M ^
