Is this a bug or am I missing something?
[code] Dim s as single = 3/7
Dim d as double = 3/7
Dim t1 as string = str(s, “-0.###”)
Dim t2 as string = str(d, “-0.###”)
break[/code]
After the break:
t1 = 0.4285714 (with 7 decimals!!!)
t2 = 0.429 (correctly 3 decimals)
If a single doesn’t work, a double no problem.
I’m not sure that # limits decimal places on the right side of the decimal point. Have you tried “-0.000” ?
0 instead of # does indeed work for this, I’ve used it many times now.
No. This is not the solution.
[code] Dim s as single = 3/7
Dim d as double = 3/7
Dim t1 as string = str(s, “-0.###”)
Dim t2 as string = str(d, “-0.###”)
Dim t3 as string = str(s, “-0.000”)
Dim t4 as string = str(d, “-0.000”)
break[/code]
gives:
t1 = 0.4285714 (with 7 decimals!!!)
t2 = 0.429 (correctly 3 decimals)
t3 = 0.4285714 (with 7 decimals!!!)
t4 = 0.429 (correctly 3 decimals)
Besides, # and 0 are not the same. I want to use # because it writes nothing when you have zeros at the right end.

Str( 95.65, “##.##” ) would use the . as the decimal separator no matter what the users locale setting is.[/quote]

Use the new framework :
[code] Dim s as single = 3/7
Dim d as double = 3/7
Dim t1 as string = s.ToText(Xojo.Core.Locale.Current, “#,###.###”)
Dim t2 as string = d.ToText(Xojo.Core.Locale.Current, “#,###.###”)
break[/code]
Thank you Michel for your workaround.
But this is not the solution, as I will explain later.
In fact it’s much easier to declare the variable as double and everything is solved. That is what I have done and now everything works, however there is a bug (that is obvious) that must be solved or at least it should be warned at the LR. I lost some hours finding the problem, because I never thought that something so simple could give any problem.
About your proposal:
[quote]Methods
ToText(Extends value As Single, Optional locale As Locale) As Text
Converts a Double value to a Text value using the specified locale.
Examples
Dim s As Single = 123.45
Dim t As Text
t = d.ToText // t = “123.45”[/quote]
incongruently uses Single but explains: Converts a Double…
Dim t0 as String = s.ToText(Xojo.Core.Locale.Current, "-0.###")
Dim t1 as string = str(s, "-0.###")
Dim t2 as string = str(d, "-0.###")
I get:
t0 = -0,429 (negative and comma as decimal separator)
t1 = 0.4285714 (with 7 decimals!!!)
t2 = 0.429 (correctly 3 decimals)
It is really a chaos!!!

Take that post and file a specific Documentation bug report with a copy/paste. I am sure Paul lefebvre will be glad to sort this out.
