extend (dyad)

Form: tacit
Extend the last item of a list.

Syntax

(N)extend(L)
N = number of items in the extended list
L = list to be extended

Example

   (12)extend(1.01 1.02 1.03)
1.01 1.02 1.03 1.03 1.03 1.03 1.03 1.03 1.03 1.03 1.03 1.03

   (2)extend(1.01 1.02 1.03 1.04 1.05)
1.01 1.02

   (15)extend('asd')
asddddddddddddd

   (6)extend('ad';1;2;'ZZ')
┌──┬─┬─┬──┬──┬──┐
│ad│1│2│ZZ│ZZ│ZZ│
└──┴─┴─┴──┴──┴──┘

extenda (dyad)

Form: tacit
Extend the last item of a list.
Similiar to extend except reversed.

Syntax

(L)extenda(N)
N = number of items in the extended list
L = list to be extended

Example

   (1.01 1.02 1.03)extenda(12)
1.01 1.02 1.03 1.03 1.03 1.03 1.03 1.03 1.03 1.03 1.03 1.03

   (1.01 1.02 1.03 1.04 1.05)extenda(2)
1.01 1.02

   ('asd')extenda(15)
asddddddddddddd

   ('ad';1;2;'ZZ')extenda(6)
┌──┬─┬─┬──┬──┬──┐
│ad│1│2│ZZ│ZZ│ZZ│
└──┴─┴─┴──┴──┴──┘

steps (monad)

Form: tacit
Generate uniform steps over a closed interval.
The end points of the interval are inculded.

Syntax

steps(A,B,N)
A = lower limit of range
B = upper limit of range
N = number of steps in the interval

Example

   steps(0,10,5)
0 2 4 6 8 10

   steps(1.0,1.1,10)
1 1.01 1.02 1.03 1.04 1.05 1.06 1.07 1.08 1.09 1.1
