 For ARM CPUs that support IEEE floating-point exceptions, the behavior on Windows is as follows:
 
 - **Arm32**: Windows doesn't support floating-point exceptions.
-- **ARM64**: For processor variants that support hardware floating-point exceptions, Windows delivers them.
+- **Arm64**: For processor variants that support hardware floating-point exceptions, Windows delivers them.
 - **Arm64EC**: For processor variants that support hardware floating-point exceptions, Windows catches these exceptions and disables them in the FPCR register. This ensures consistent behavior across different processor variants.
 
 - The [`_set_controlfp`](/cpp/c-runtime-library/reference/controlfp-s) function on ARM platforms correctly changes the FPCR register when unmasking floating-point exceptions. However, instead of raising an unmasked exception, Windows resets the FPCR register to its defaults every time an FP exception is about to be raised.
