Math students will appreciate TI36X's ability to perform fractional equations and calculate angle units (radians, grads, degrees) when performing trigonometric functions. Everyone will find the calculator's English/metric conversions helpful.
The TI36Xs single-line LCD is a little difficult to read when the unit is lying on a desk, and users in need of graphing functions will have to look elsewhere. Overall, however, for a calculator in this price range, the TI36X provides enough power for most high-level math and science needs.
However, consider this calculation and its result:
(262144 * 4096) - (2^18 * 2^12) = -0.01
The correct answer, obviously, is 0. That may be a silly calculation to perform, but I actually did this once as a check.
TI's support - via email - suggests that this is a normal rounding error. I am not sure that this is acceptable in a calculator of this class. The size of the operands doesn't seem unreasonably large.
If it were not for that, I would give the calculator 4 stars. It's really too bad because I like the layout of this calculator MUCH better than that of the Casio. But I worry about getting other errors that won't be immediately obvious to me.
I can't prove one or the other how likely this rounding error is to happen in "typical" calculations.
