The arduino spec says that a byte is "an 8-bit unsigned number, from 0 to 255" so not sure why this isn't working. Here's the Java code and output, int id = input.read (); LOG.info ("id " + id); "INFO: id 65533"

WebSep 25, 2024 · Float Data Type. Float is an approximate number data type used to store a floating-point number. float (n) - n is the number of bits that are used to store the mantissa in scientific notation. Range of values: - 1.79E+308 to -2.23E-308, 0 and 2.23E-308 to 1.79E+308. Storage size: 4 Bytes if n = 1-9 and 8 Bytes if n = 25-53 – default = 53. Webvalue is less than Byte.MinValue or greater than Byte.MaxValue. Examples The following example uses the ToByte method to convert decimal numbers to Byte values.
WebPrimitive values do not share state with other primitive values. The eight primitive data types supported by the Java programming language are: byte: The byte data type is an 8-bit signed two's complement integer. It has a minimum value of -128 and a maximum value of 127 (inclusive). The byte data type can be useful for saving memory in large ...
