Figure 23. The FPU Registers Window

Choose FPU Registers from the Data menu to open the FPU window.  This window
displays the current value and status of all the FPU registers.  If you are
debugging a program that uses Intel 8087 emulation, this window display the
contents of the emulator's data area.  You can change a value by
double-clicking on, it or by cursoring to it and pressing ENTER.  Press the
right mouse button to access the following pop-up menu items:


Modify
    Change the value of the selected register, or bit.  You will be prompted
    for a new value, unless you are modifying a bit.  A bit will toggle
    between 0 and 1.

Hex
    Toggle the FPU window display between hexadecimal and floating point
    display.  This menu item sets options on a per-window basis, overriding
    the global settings.  When you use the menu item to change these
    settings, they will not be saved between debugging sessions.  To change
    an option permanently, see The Window Options Dialog.
