Hi,
i need the operation Math.log() for determining a value in an output model. Although not included in OCL, ATL does provide mathematical operation as cos(), sin(), tan(), acos(), asin(), toDegrees(), toRadians(), exp(), log(), sqrt() according to http://wiki.eclipse.org/ATL/User_Guide_-_The_ATL_Language. Is there anything similar in QVTo or a workaround to calculate the logarithm of a Real number?
I appreciate your help,
Henning

HI
FYI; the OCL specification is moving to a modeled library that then
becomes easily extensible. It also supports third party domain libraries.
This is available with the new Eclips OCL in the Examples plugins, but
is not yet accessible from QVTo.
