ccx crashes when a force has too many digits like this:
FemConstraintForce,2,1.5966711853290134e-18
but it's OK with that format:
FemConstraintForce,2,1.5966711853e-18
An example of ccx error:
*ERROR reading *CLOAD. Card image:
FEMCONSTRAINTFORCE,3,1.5966711853290134E-18
This commits adds formatting to make sure the numbers are within ccx
limits.
