Splet13. mar. 2014 · The integer constant 32767 is, in hex, 0x00007FFF. A byte is a signed 8-bit type. Casting (byte)0x00007FFF effectively truncates the upper 24 bits, leaving 0xFF. Since it is signed, this represents -1. Assigning it back to a short doesn't change the value because it's already been converted to a byte, and -1 is within range of a short. Splet11. apr. 2024 · Address is outside of memory allocated for variable. One of my students was trying to port some pure C code to OpenCL kernel at a very early stage and encountered a problem with RX580 dGPU while using clbuildprogram. In the meantime, the code has no building problem with RX5700 dGPU and CPU runtimes (pocl3 and intel CPU runtime). character development through dialogue

Splet18. mar. 2024 · 2 Answers Sorted by: 4 0x8000 is firstly interpreted as an integer with the value 32768, and then Java attempts to convert that to a short, which it is then unable to do, because 32768 doesn't fit into a short. Note that just using 32768 instead also gives the same result: short x = (short)32768; System.out.println (x); // -32768 Splet01. sep. 2013 · 1 thru 32767 = 37267 values 0 = 1 value -1 thru -32768 = 32768 values ----- 65536 values Both ones' complement and sign-magnitude encoding allow for a negative-zero value (as well as positive-zero), meaning that one less bit pattern is available for the non-zero numbers, hence the reduced minimum range you find in the standard.
