Generates inline code for transcendental functions.

/Qfast_transcendentals  

This compiler option forces transcendental functions to be converted to inline code to improve execution speed. This option has an effect only when paired with /fp:except or /fp:precise. Generating inline code for transcendental functions is already the default behavior under /fp:fast.

This option is incompatible with /fp:strict. See /fp (Specify Floating-Point Behavior) for more information about floating point compiler options.

To set this compiler option in the Visual Studio development environment

  1. Open the project's Property Pages dialog box. For details, see How to: Open Project Property Pages.

  2. Click the C/C++ folder.

  3. Click the Command Line property page.
