## Define options AMCnumericChoices as variables

Added by Javier G 11 months ago

I would like to know if there is any way to define the option "exact"

in AMCnumericChoices as a variable calculated with fp package. T

tried the following but obviously it doesn't work:

\AMCnumericChoices{\solution}{digits=5,decimals=2,sign=true,borderwid

th=0pt,backgroundcol=lightgray,exact=0.05*{\solution},scoreexact=1}

Thank you in advance.

I think you have to compute `100*0.05*\solution`

with `fp`

and pass the result.

Note that `exact`

should be an integer.

With `digits=5,decimals=2`

, numbers are written XXX.XX

Answers are considered as correct if `abs(XXXXX-YYYYY)≤exact`

, where YYY.YY is the correct value.

Exemple: if the correct value is 10.34 and `exact=7`

, 10.39 is a correct answer because abs(1034-1039)=5≤7.

Many thanks for your quick response| I had forgotten that "exact" option must be an integer
