.format ?

[MAGNET]

Hello Gintaras

I need to append a variable amount of zero's to a string variable. I can do it using function "for". After some reading in Qm help i found that function "format" maybe could do it too(?) just cant work it out.

How i do it.

Code:

str s = "5"
int z = 2  ;; amount of zero's

for(_i 0 z) s + "0"

out s

Code:

Copy      Help

str s = "5"
int z = 2 ;; amount of zero's

s.set('0' s.len z)

out s

With str.format also possible in QM 2.3.3.

Code:

Copy      Help

str s = "5"
int z = 2 ;; amount of zero's

s.formata("%.*m" z '0')

out s

But in this case better is str.set. Your code also OK, when z is not too big. Even shorter is: rep(z) s + "0"
