Returns the function $f: x \mapsto \bold{1}(k \leq n)$, that maps $k$ to $1$ if $k \leq n$ and $0$ otherwise. The argument n must be an integer or the function fails.
n: the end of the interval that the zedfunc will map to 1
Example
show scalar "" a1b2 with uniform.left(5)
Errors
Calling uniform.left with a non-integer argument will fail and return the following error:
‘uniform.left(n)’ is rounding fractional numbers.
Recipes and best practices
uniform.left can be used to modify another zedfunc by setting its values to 0 after a certain point:
// This function maps negative integers to themselves and positive integers to 0
f2 = linear(1) * uniform.left(0)
