numeric conversions?

Hello,

me again :(
i just ran into another problem....
didn't found it neither in the doc nor in the FAQ.....

the currencies conversion factors i use are stored as float4 in a table,
the values to apply on are stores as int4 ....

is the type casting done automaticly? how? can i have an influence of
the cast order? is there an easy way to doing the rounding?

the operation i want to do is something along this line:

int4 = ((int4) float4 * (float4)int4 +.5);
