Kwiecinski, Martin, Stasto [13] argue for inclusion of DGLAP terms into BFKLevolution of unintegrated gluon density. The equation was reformulated byOliveira, Martin, Ryskin [6] employing the opening angle {\theta} = k/xp as theevolution variable. It leads to a description of a {\theta}-integrated gluondensity. This paper is a numerical study of these two similar combinedBFKL+DGLAP formulations. It is a demonstration of feasibility of the newapproach. The different ways of subtracting the contribution common for BFKLand DGLAP proposed in [13] and [6] are compared. The numerical tests confirmthat the {\theta} variable is a more natural evolution variable for this kindof equation.
