David,
Which value do you think is set wrong. Other than the '-' minus sign in front of one of the values, these are all correct.
Before using any intrinsic, you will need to look in the C Compiler User's Guide for the definition of these intrinsics. The Compiler UG also shows the instruction that is used for the intrinsics, so you can look at the complete definition in the CPU & Instruction Set Reference Guide where all the assembly instructions are described in detail.
All intrinsics are tools for accessing these special assembly instructions that are not routinely used by the C Compiler.
There is not an assembly instruction for performing the square root function directly, but you may be able to use these two intrinsics if their definitions fit what you need.
Please let us know if you are unable to find this information in the C Compiler UG.
Regards,
RandyP
