I'm trying to pass unsigned int number to vertex shader, but the shader acts like it gets only the first byte of that number.

Vertex structure:

struct HMMULTITEX
{
D3DXVECTOR3 pos;
D3DXVECTOR3 norm;
D3DXVECTOR2 tex;
UINT texID;
};

Vertex declaration

D3DVERTEXELEMENT9 aVertDecl[] =

{
{ 0, 0, D3DDECLTYPE_FLOAT3, D3DDECLMETHOD_DEFAULT, D3DDECLUSAGE_POSITION, 0 },
{ 0, 12, D3DDECLTYPE_FLOAT3, D3DDECLMETHOD_DEFAULT, D3DDECLUSAGE_NORMAL, 0 },
{ 0, 24, D3DDECLTYPE_FLOAT2, D3DDECLMETHOD_DEFAULT, D3DDECLUSAGE_TEXCOORD, 0 },
{ 0, 32, D3DDECLTYPE_UBYTE4, D3DDECLMETHOD_DEFAULT, D3DDECLUSAGE_TEXCOORD, 1 },
D3DDECL_END()
};

HLSL code:

unsigned int vTexHeight : TEXCOORD1
out float oTH[8] : TEXCOORD3

unsigned int retnum=vTexHeight % 0x10;
oTH[0]=(retnum/15.0f);
	
retnum=vTexHeight/0x10;
retnum=retnum % 0x10;
oTH[1]=(retnum/15.0f);

retnum=vTexHeight/0x100;
retnum=retnum % 0x10;
oTH[2]=(retnum/15.0f);

retnum=vTexHeight/0x1000;
retnum=retnum % 0x10;
oTH[3]=(retnum/15.0f);

...oTH[7]

Problem: Only oTH[0] and oTH[1] works, all other ale allways 0. It looks like vertex shader gets only the first byte of vTexHeight.
Everything above 0xff is ignored.
How can i pass unsigned int to vertex shader? Why is current vertex shader ignoring anything above the first byte?

Thanks for the tip, i changed D3DDECLTYPE_UBYTE4 to D3DDECLTYPE_D3DCOLOR and unsigned int vTexHeight to float4 vTexHeight. Now i get bytes with

int u1=(int)(vTexHeight.b*255);
int u2=(int)(vTexHeight.g*255);
int u3=(int)(vTexHeight.r*255);
int u4=(int)(vTexHeight.a*255);
