VCVT

Hello all,
               We are facing an issue with conversion from float to integer

the following parallel instruction seems to be working...
vcvt.f32.s32 q0,q0     @ converting rect[0] tr.x,y tr.width,height to float
vcvt.f32.s32 q1,q1     @ converting rect[1] tr.x,y tr.width,height to float

the same thing when tried the other way, ie float to integer seems to be going wrong. Doesnt seem to be rounding to the nearest integer, rather truncating the decimal part and returning the int.
vcvt.s32.f32 q0,q0     @ converting rect[0] tr.weight,a,b,cto int
vcvt.s32.f32 q1,q1     @ converting rect[1] tr.weight,a,b,cto int

but if we put each single precesion instruction it seems to be working
vcvt.s32.f32 s0,s0
vcvt.s32.f32 s1,s1
vcvt.s32.f32 s2,s2
vcvt.s32.f32 s3,s3

kindly suggest if we are doing anything wrong.

thanks and regards
pachu
