java中将字节数组转为float

ByteBuffer.wrap(array).getFloat();
float f = ByteBuffer.wrap(bytes).order(ByteOrder.LITTLE_ENDIAN).getFloat();

float foo = Float.intBitsToFloat( buffer[n] ^ buffer[n+1]<<8 ^ buffer[n+2]<<16 ^ buffer[n+3]<<24 );

float fromByteArray(byte[] bytes) {
     return bytes[0] << 24 | (bytes[1] & 0xFF) << 16 | (bytes[2] & 0xFF) << 8 | (bytes[3] & 0xFF)
}
