FAQ:
* If you want data size conversions in multiples of 1024, use kibibytes, mebibytes, gibibytes, etc – see en.wikipedia.org/wiki/Kibibyte.

* If the percent key appears to give wrong answers, make sure you are pressing ‘=’ at the end, e.g. ’25 + 10 % =’ will give 27.5.

* If sin/cos/tan functions don’t give the answer you are expecting, make sure you are in the correct angle mode. Degrees, radians and grads are supported, indicated by DEG, RAD, GRAD in the display. Use the DRG key to change mode.

* If any of the digit keys are disabled, or the decimal point doesn’t work, or you have answers with letters in, or basic arithmetic appears to be wrong, then you are in binary, octal or hexadecimal mode. Press DEC to return to decimal operation. If you don’t need these modes, please make sure that ‘Enable Radix Modes’ is disabled in the settings.
