RAISE2(x,n) returns the value x*(2**n).
>>-RAISE2(x,n)-------------------------------------------------><
- x
- Expression. x must have a computational type.
- n
- Expression. n must have a computational type.
If x is REAL FIXED BIN(p,0) and SIGNED, the result is SIGNED REAL FIXED BIN(r,0) where if p <= M1, r = M1; if p > M1, r = M2.
If x is REAL FIXED BIN(p,0) and UNSIGNED, the result is UNSIGNED REAL FIXED BIN(r+1,0) where if p <= (M1+1), r = (M1+1); if p > (M1+1), r = (M2+1).
Otherwise, x is converted to SIGNED REAL FIXED BIN(p,0) and the result has the same attributes as above.
If n is negative or if n is greater than r, the result is undefined.
Note: RAISE2(x,n)
is equivalent to the assembler SLA(x,n).
Example
raise2(6,1) /* produces 12 */
