I'm trying to get the decimals in simple division but is always returning zero:
(lldb) po Double(20 / 100)
0.0
(lldb) po Float(20 / 100)
0.0
Any of you knows why is returning zero? or there is a way to get the of 0.20
?
I'll really appreciate your help
20 / 100
is an integer division, and so is 0 (since 100 > 20). That 0 is passed to Double.init
.
You want floating point division:
20.0/100.0
You can also use 20.0/100
since a Double divided by an Int is a Double, or 20/100.0
for the same reason.
None of these will return 0.20 exactly, since that can't be represented by Double . 20.0/100
is 0.20000000000000001. But I assume this is what you're looking for.
