Select Options->Debugger settings->Default data representation to specify how you want your data represented in the monitors. A cascading menu appears with choices for "system" and for the languages supported by the debugger.
System: You can select either floating point or hexadecimal. This setting affects only the representation used for floating point registers in the Registers monitor.
Language-specific representations: For each language supported by the debugger, a cascading menu choice appears from the Default data representation menu. The dialog for the language you select contains a group box for each data type that is supported by the debugger's expression evaluator for that language. You can change the default representation for a data type by clicking on the appropriate radio button within that data type's group box.
