Several display modes are provided. The top 4 modes are all base 10, and they
present the number in different formats. The last 3 modes convert the number to
a different base. You can use the display mode to convert from one base to another. For instance,
if you wish to see what the decimal value is of Hex number 0xff02, you would enter
the number in "Hex" mode, then change the mode to "Fix" and the number will be
shown in decimal form.
- Fix: Fixed number of decimal places, according to the 'Precision' selection.
The requested number of decimal places will be rounded to fit into the display.
If the number cannot be represented meaningfully in this mode then the number will
be presented in 'Sci' form.
- Sci: Exponential display, with one significant digit and a fixed number
of decimal places, according to the 'Precision' selection.
- Eng: Like 'Sci' mode, but the exponent will always be a multiple of 3, so
there may be up to 3 significant digits.
- Frac: Fractional, instead of decimal, display. The denominator of the fraction
will be selected from the 'precision' list. The fraction will round to the
smallest denominator; for instance, 3 32/64 will round to 3 1/2, but 3 31/64 will
not round.
- Bin: Binary numbers will be represented as the least significant 8 bits.
- Oct: Octal numbers will be represented as the least significant 4 bytes.
- Hex: Hexidecimal numbers will be represented as the least significant 4 bytes.
