I am using Proj4js along with OpenLayers for the transformation of x,y (projection type is Transverse Mercator) to long, lat.
While executing "inverse()" method what I noticed that in tmerc.js some "this.ep2" parameter is used with in the formula and the value of this parameter is "NaN".
Because of this the transformation is not working.
I am guessing that this is happening because perhaps I am not initializing required parameter with in the definition file of the source coordinate system.
So, could anyone help me in knowing which parameter for "this.ep2" has to be passed in definition file?
Thanks in advance
