vec.zeros

signature

vec.zeros(int) -> list

What it does

A list of n ints, all 0. For zeros as floats multiply by 0.0, or use vec.full(n, 0.0).

print(vec.zeros(3))print(vec.zeros(0))

output

[0, 0, 0][]

The items are ints, so arithmetic on them stays in ints until a float is mixed in.
A whole float counts as the int it is: vec.zeros(2.0) is [0, 0].
At most ten million items.

print(vec.zeros(2) | vec.add(1))print(vec.zeros(2) | vec.add(0.5))print(vec.zeros(2.0))print(vec.full(2, 0.0))

output

[1, 1][0.5, 0.5][0, 0][0.0, 0.0]

A negative count, or one over ten million, is a runtime error, not an error value; so is a count that is not an int.

this one fails

print(vec.zeros(-1))

output

line 1: `vec.zeros`: -1 is not a count from 0 to 10000000

this one fails

print(vec.zeros("3"))

output

line 1: `vec.zeros` expects an int as argument 1, got str

A row of counters to add into, or a blank matrix built from rows:

print(vec.zeros(4) | len)print(range(2) | map((i) => vec.zeros(3)))

output

4[[0, 0, 0], [0, 0, 0]]
