Callable Signatures

namespace eve
{
  template<eve::floating_value T> constexpr T oneotwoeps(as<T> x) noexcept;
}

Parameters

• x : Type wrapper instance embedding the type of the constant.

Return value

The call eve::oneotwoeps(as<T>()) returns elementwise, the smallest positive value x of the type such that 1+x != x.

• If T is an integral value the elements returned are equal to one.
• If T is a floating value the elements returned are equal to:
  • 4194304 if the elements type is float.
  • 2.2518e+15f if the elements type is double.
