** Using WeBWorK **

Hi!

i'm having a problem trying to use the alternate decimal context with the scientific notation context. It doesn't seem to permit the use of the coma with the scientific notation. Is there a workaround for this to be possible.

Here is my code:

# DESCRIPTION

## KEYWORDS('Scientific Notation')

DOCUMENT();        

loadMacros(

  "PGstandard.pl",

  "MathObjects.pl",

  "contextScientificNotation.pl",

  "contextAlternateDecimal.pl",

);

TEXT(beginproblem());

BEGIN_TEXT

<style>

ol.alpha {

    counter-reset: alpha;

    display: table;

    padding:15px;  

}

ol li {

    display: table-row;

}

ol li span{

    display: table-cell;

    text-indent: 0px;

}

ol.alpha > li:before {

    margin-right: 0.5rem;

    font-weight: bold;

    counter-increment: alpha;

    content:counter(alpha, lower-alpha)") "

}

ol ul.a li{

    display:list-item;

    list-style-type: disc;

    list-style-position: outside;   

}

ol ul.a {

    padding-right: 20px;

}

</style>

$exp2 = 5;

$exp31 = random(-1,-3);

$exp41 = random(-6,-4);

$decimalNumber4 = (random(100,900,10)+random(1,9,1))*10**$exp41;
