Operating Modes

WRPN has 5 operating modes:

Click on the HEX, DEC, OCT, or BIN buttons to enter the appropriate mode.

The FLOAT function is a "yellow" function above the RCL button. FLOAT requires an argument which is the decimal precision. For example, to switch to floating point mode with 2 decimal places, enter the following sequence:

FLOAT (use CTRL, then RCL)
2

The float mode will switch to scientific notation whenever the display would otherwise loose precision at the specified number of decimal places. To force scientific notation, enter a decimal point as the float digit.

Optionally, each of the operating modes can be selected from the window's Menu.

The internal representation of the numbers do change when switching between the floating point and any one of the integer modes. In some cases, the values may appear to be the same. However, do not rely on this behavior. For example, the fractional parts of floating point number will be truncated upon entering one of the integer modes... and will not be restored upon return to the floating point mode.

The range of valid input characters is shown below:

Hex [0-9] [a-f]
Float [0-9] (plus decimal point)
Dec [0-9]
Oct [0-7]
Bin [0-1]
