randx = (randx * 1103515245) + 12345 ;

/*keep 30 bits*/
/*range 0 to 0.99999...*/
/*range 0 to <L+H+1*/
/*truncate to integer*/
/*range -L to H*/
} ;
(3) Using the libraries, apply DCT then reverse DCT conversion to each block, named BLK[n] (where n is
a number between 0 and 19999). The output value is specified as OUT[n][64] (where n is a number
between 0 and 19999).
(4) Calculate the following errors between BLK[20000][64] and OUT[20000][64].
<1>
Maximum error
<2>
Mean square error for each element number
<3>
Mean square error for all elements
<4>
Mean error for each element number
<5>
Mean error for all elements
