 Intel x86-derived platforms support the DENORMAL input and output values in hardware. The x86 behavior is to preserve DENORMAL values. The ARM and ARM64 platforms and the x64 platforms that have SSE2 support enable DENORMAL operands and results to be flushed, or forced to zero. The **_controlfp** and **_control87** functions provide a mask to change this behavior. The following example demonstrates the use of this mask.

-### Hexadecimal Values

 For the **_MCW_EM** mask, clearing the mask sets the exception, which allows the hardware exception; setting the mask hides the exception. If a **_EM_UNDERFLOW** or **_EM_OVERFLOW** occurs, no hardware exception is thrown until the next floating-point instruction is executed. To generate a hardware exception immediately after **_EM_UNDERFLOW** or **_EM_OVERFLOW**, call the **FWAIT** MASM instruction.
