Hi all,
Can someone explain what I should do to make the following conditional
hint work such that a response within $tolTKwrongans of $TKwrongans
triggers the conditional hint? Currently the conditional hint text
only appears when the response it exactly $TKwongans to as many decimal
places as the computer calculates. (Apparently the responseparam does
not work the way I assumed it would...?)
<numericalresponse answer="$ans" unit="J/g/K" format="1E">
<hintgroup>
<numericalhint answer="$TKwrongans" unit="J/g/K" format="1E"
name="TKwrong">
<responseparam name="tolTKwrong" type="tolerance"
description="tolerance on answer to trigger numerical hint"
default="$tolTKwrongans" />
</numericalhint>
<hintpart on="TKwrong">
<startouttext />The conditional hint text would go here.
<endouttext />
</hintpart>
</hintgroup>
<responseparam name="tol" type="tolerance" description="Numerical
Tolerance" default="$tolans" />
<responseparam name="sig" type="int_range,0-16" default="0,15"
description="Significant Figures" />
<textline />
<hintgroup>
<startouttext />The general hint text goes here.
<endouttext />
</hintgroup>
</numericalresponse>
Thanks,
Ray
