Re: sprintf on floating point

<wrong>$_ = sprintf('%.f',sprintf('%1.2f', 2e-7))</wrong>

How about that?

UPDATE: sorry, i didn't test this. The '0+' approach is much better.

`perl -e 'print sprintf "%f", sprintf "%0.2f", 0.1' 0` [download] However, you could do it this way (though without using sprintf): `perl -e 'print 0 + sprintf "%0.2f", 0.001' 0 perl -e 'print 0 + sprintf "%0.2f", 0.1234' 0.12` [download] Does that help? -- Dan	[reply] [d/l] [select]

It does help however the first one doesn't work.	[reply]

There's one tiny little problem with this: 0.12345 becomes 0 too. That should become 0.12	[reply]
