int16 function

int int16(
  1. int value
)

Implementation

int int16(int value) {
  // Mask to 16-bit unsigned integer
  int maskedValue = value & 0xFFFF;

  // Check if the value is larger than the max int16_t range
  if (maskedValue > 0x7FFF) {
    // Convert to a negative int16 by subtracting 2^16
    return maskedValue - 0x10000;
  } else {
    // Return as is if it's within the int16 range
    return maskedValue;
  }
}
