arithmetic shift bits
 
Description

i3 ishift(i1, i2)
ishift(i1, i2) produces the result of shifting the bits in i1 by i2 positions. Positive values of i2 shift to the left with zero fill; negative values shift to the right with sign extension. Vacated bit positions are zero-filled.
 
Parameters
i1
a 32 bit integer
i2
an integer
returns
the result of a Arithmetic SHIFT operation
 
Errors
101 i1 or i2 is not an integer
