Callable Signatures

namespace eve
{
   // Regular overload
   constexpr auto flush_denormal(value auto x)                          noexcept; // 1
   // Lanes masking
   constexpr auto flush_denormal[conditional_expr auto c](value auto x) noexcept; // 2
   constexpr auto flush_denormal[logical_value auto m](value auto x)    noexcept; // 2
}

Parameters

• x: value.
• c: Conditional expression masking the operation.
• m: Logical value masking the operation.

Return value

1. denormal values are flushed to zero.
2. The operation is performed conditionnaly.
