57 * a problem to do in integer arithmetic. We multiply all the constants
121 /* Multiply an INT32 variable by an INT32 constant to yield an INT32 result.
124 * 16x16->32 bit multiply can be used instead of a full 32x32 multiply.
129 #define MULTIPLY(var,const) MULTIPLY16C16(var,const)
131 #define MULTIPLY(var,const) ((var) * (const))
137 * are 16 bits or less, so either int or short multiply will work.
