Format issue

[wp]

The RTL function "Format" has problems when the format specifier is "%0.9" and the number is between 1e8 and less than 1e9, e.g.

Format('%0.9', [1e8]) --> 1
Format('%0.9', [1.2e8]) --> 12

How's that?

I think you miss the ArgType part (it's NOT optional AFAIK), I even wonder why it doesn't generate runtime errors.

@I even wonder why it doesn't generate runtime errors.

Both give EConvertError here.

There must be something like:

Code: [Select]

Format('%0.9f', [1e8]);
Format('%0.9f', [1.2e8]);

Sorry, I am embarrassed - I forgot the "g". The first posting should read:

Format('%0.9g', [1e8]) --> 1
Format('%0.9g', [1.2e8]) --> 12

[Blaazen]

Then I cannot confirm here. It formats as expected:
Format('%0.9g', [1e8]);
Format('%0.9g', [1.2e8]);
100000000
120000000

A windows issue? I am using Win7, FPC 2.6.0 and a recent snapshot of Lazarus.

Since it's part of RTL, it has nothing to do with Lazarus. You might want to check the bugtracker for bugs regarding this function.

w32:
I get 1 and 12 with fpc 2.6

But it looks ok with 2.4.4 and 2.7.1 (2.7.1 from a while ago)

So it may be fixed already. I haven't tested 2.6.1

It looks fine with 2.6.1
