i2s

convert integer to short integer

Description

Converts an integer to a signed short. A 32-bit int is popped off the stack, the top 16 bits are set to zero, and the resulting value is then sign extended to an int. The int result is pushed back onto the stack.

i2s is used in Java where there is an explicit case between an int and a short. Notice that i2s can cause a change in sign. For example, in the code:

     int x = -40000;     short s = (short)x; 

The value of s is positive 25536, since the sign bit of x is lost in the conversion.
