$N: Numeric Coprocessor Switch
Switches between the two different models of floating-point code generation supported by the compiler.
Syntax: {$N+} or {$N-}
Default: {$N-}
Type: Global
Menu Command: Options|Compiler|80x87
The $N- State
In the $N- state, the compiler generates code to perform all real-type calculations in software by calling run-time library routines.
The $N+ State
In the $N+ state, the compiler generates code to perform all real-type calculations using the 80x87 numeric coprocessor and gives you access to four additional real types: Single, Double, Extended, and Comp.
Note: You can also use the $E+ directive to emulate the 80x87. This gives you access to the IEEE floating-point types without requiring that you install an 80x87 chip.
