# How should I deal with a large coefficient?

When I was trying to control the scale of coefficients in my constraints, I multiplied them by a small constant, such as 10^{-10}. However, it raises a new problem.

I get Error(1400): buc[1] is too small.
How should I do for this?

MSK_RES_ERR_INFINITE_BOUND is an error you will get when you actually have a bound like expression >= \infty. Try with a smaller model to detect where they come from. Hard to give any specific advice except that you should carefully check everything in your model.
