<div>Hi Folks,<br>
</div>
<div><br>
</div>
<div>I am migrating a package from Cog to Spur and I am getting errors that I suspect are related to it.<br>
</div>
<div><br>
</div>
<div><br>
</div>
<div>Here is an example:<br>

<div><br>
</div>
<div>
<blockquote style="border: 1px solid rgb(204, 204, 204); padding: 7px; background-color: rgb(245, 245, 245);">
<div>|result|<br>
</div>
<div> result := pairs inject: first<br>
</div>
<div> into: [ :base :pair |<br>
</div>
<div> (pair first = 'round')<br>
</div>
<div> ifTrue: [<br>
</div>
<div> (pair last >= 0)<br>
</div>
<div> ifTrue:[<br>
</div>
<div> (base >=0)<br>
</div>
<div> ifTrue:[<b>"Cannot store into ->"</b>base := base roundUpTo: ((1/10) raisedTo:(pair last truncated)) asFloat]<br>
</div>
<div> ifFalse:[base := base roundDownTo: ((1/10) raisedTo:(pair last truncated)) asFloat]]<br>
</div>
<div> ifFalse:[<br>
</div>
<div> (base >=0) <br>
</div>
<div> ifTrue:[<br>
</div>

</div>
<div> ifFalse:[base := base roundUpTo: ((1/10) raisedTo:(pair last truncated)) asFloat]]]].<br>
</div>
<div><br>
</div>
<div> transcripton ifTrue:[Transcript show:'PHPRoundSimple ' , (result asFloat); cr. ].<br>
</div>
<div><br>
</div>
<div>^ result<br>

<br>
</div>
<div>Is this related to changes in Spur?<br>
