Symptoms
Consider the following scenario:
- You create a Microsoft Visual C++ 2008 Service Pack 1 (SP1) project that contains a trigonometric method. For example, the project contains the sin() method.
- You build the project to run on the x86 and x64 platforms.
In this scenario, the value that the trigonometric method returns on the x86 platform may differ from the value that the same method returns on the x64 platform.
Cause
This issue occurs because the trigonometric method for the x64 platform is implemented as a C function. Therefore, the trigonometric method is reliant on the compiler-intrinsic and compiler-generated code.
Resolution
To resolve this issue, apply the following hotfix. This hotfix changes the trigonometric method for the x64 platform to implement the method in assembly instead of a C function. The assembly code reduces the reliance on the compiler-intrinsic and compiler-generated code. Therefore, the hotfix improves the accuracy of the trigonometric method.
