Converting two bytes into a Q15 Float (Float 16?) in Java. (Android)

I have an input of byte pairs. One pair of byte represents a Q15 float. This is a format which I cannot change, it comes from a source that I have no control on. I would need to use the two bytes and build a Q15 float (Float16?) from them. My problem is that there is very few knowledge about this on stackoverflow or any other site. I was trying to use Half, this is Android's own Float16 (or not?) but so far with less of a success. So for example I have a byte pair of: 113, 159, these two are -78.11234 in Q15 float. This is the c code which generates these Q15 byte pairs which I get in Android from a source: #define Q15_SCALE_FACTOR (32768) void float_array_2_q15_array(float* float_array, int16_t* q15_array, uint32_t array_length) { for (uint32_t i = 0; i < array_length; i++){ q15_array[i] = (int16_t)(float_array[i] * Q15_SCALE_FACTOR); q15_array[i] = ((0xff00 & q15_array[i]) >> 8) | ((0x00ff & q15_array[i]) << 8); } } I would need a Java function which converts the two given bytes to a Q15 float. So for a byte pair of 113, 159 would give me the exact number of: -78.11234 in a Q15 float.
