Callable Signatures

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

Parameters

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

Return value

1. Returns elementwise x >= 0.
2. The operation is performed conditionnaly.
