The default rounding behavior depends on the compiler’s code generation decisions and the precision parameters of the operating system. |
This option rounds floating-point results after floating-point operations. Rounding to user-specified precision occurs at assignments and type conversions. This has some impact on speed.
The default is to keep results of floating-point operations in higher precision. This provides better performance but less consistent floating-point results.
