ISRL

ISRL(x,n) returns the result of logically shifting x to the right by n places, and padding on the left with zeroes.

x

Expression. x must have a computational type.

n

Expression. n must have a computational type.

The attributes of the result are determined as follows:

• If x is REAL FIXED BIN(p,0) and SIGNED, the result is SIGNED REAL FIXED BIN(p,0).
• If x is REAL FIXED BIN(p,0) and UNSIGNED, the result is UNSIGNED REAL FIXED BIN(p,0).
• Otherwise, x is converted to SIGNED REAL FIXED BIN(p,0) and the result has the same attributes.

The result is undefined if n is negative or if n is greater than M.

If x is nonnegative, ISRL(x,n) is equivalent to LOWER2(x,n); if x is negative, ISRL(x,n) is positive, unless n=0.
