round 2

[kzn]

Hi

Any help appreciated thank you.
I have the following problem:

$number = 6478;

$value = $number/1000;

I need to round $value to the nearest 0.25 and I have no idea how to do it. In the above example this would round to 6.5.

I need it to do the following if
$number = 6695; result would be 6.75

or
$number = 6530; result would be 6.5

Any help or pointers appreciated thank you

Hi

I wound use this :

[b]function[/b] [COLOR=darkgoldenrod]kznround[/color][teal]([/teal][navy]$what[/navy][teal])[/teal]
[teal]{[/teal]
  [b]return[/b] [COLOR=darkgoldenrod]round[/color][teal]([/teal][navy]$what[/navy][teal]/[/teal][purple]250[/purple][teal])/[/teal][purple]4[/purple][teal];[/teal]
[teal]}[/teal]

For which this :

[b]foreach[/b] [teal]([/teal][b]array[/b][teal]([/teal][purple]6478[/purple][teal],[/teal][purple]6695[/purple][teal],[/teal][purple]6530[/purple][teal])[/teal] [b]as[/b] [navy]$one[/navy][teal])[/teal]
  [b]echo[/b] [green][i]"$one -> "[/i][/green][teal],[/teal][COLOR=darkgoldenrod]kznround[/color][teal]([/teal][navy]$one[/navy][teal]),[/teal][green][i]"\n"[/i][/green][teal];[/teal]

Gives this :

6478 -> 6.5
6695 -> 6.75
6530 -> 6.5

generically, isn't the way of doing this something like:

round ($number/$roundto) * $roundto;

Hi

Lol. I had a feeling that the generic form is only for powers of 10. Wrong as usually. Thanks, jpadie.
