Converting Integer to Character Arduino: Converting an integer to character is an easy process. However, this type of casting i. e. char c=(char)i; is only limited integers that are between and inclusive of 0 and 127. Conversion of any integer above the value of 127 using this method yields errors in manipulation and comparison.

Output: FFFFFFFF FF. @matthijskooijman This is well defined behavior also. As the signed bit pattern of a is -1 in a char, then the unsigned long gets the bit pattern which represents the same number as if it were signed (All 1's). . If the destination type is unsigned, the resulting value is the least unsigned integer congruent to the source integer. . To maintain the -1 value, the sign bit
