We're glad you came by, but you might find what you're looking for elsewhere. TI-Basic Developer is not the site it once was. While its information on commands and other calculator features remains almost second-to-none, its forum, archives, and even hosting service, Wikidot, have been decaying for years. The calculator community would love to see what you're working on, or help you in your next coding adventure, but TI-Basic Developer is no longer the place to do it. Instead, you should head over to Cemetech (primarily American) or TI-Planet (primarily international). Both are active, well-established forums with their own archives, chatrooms, reference material, and abundant coding tools and resources. We'll see you there, we hope. |

The calculator can work with numbers written in three bases: decimal (the usual), binary, and hexadecimal. The 0h command indicates that a number is written in hexadecimal:
:0h10
16
:0h2F6
758When written in hexadecimal, numbers are expressed as signed 32-bit integers (32 bits correspond to 8 hexadecimal digits), which means that only the integers between -231 and 231-1 can be expressed in hexadecimal. With other hexadecimal-related commands, numbers are simply truncated to fit in this range. Not so with 0h: if you enter more than 8 hexadecimal digits after the 0b, the result is a domain error.
Even if the calculator is in hexadecimal mode, you still have to write 0h for an integer to be interpreted as hexadecimal: the mode setting only affects output. If the calculator is in decimal mode, which is the default, you have to use ▶Hex to get output in hexadecimal.
Error Conditions
260 - Domain error happens when 0h is used with more than 8 hexadecimal digits after it.
