[Help-glpk] type of variables

[name name]

Hello,

I have a very strange problem

I solve un Lp problem but the and the value of my  variables are not ineger I got x(0,1)=0.2... even thaught when I print the type of my variables I got 3 coresponding to type binary( I got type to binary for all variables with GLPK.glp_set_col_kind(lp, i, GLPKConstants.GLP_BV)).

Can you tell my where the problem could be?

Thank you
