esv::cos

Our animals love each other.

esv::cos

esv::cos is a function object of class esv::cos_class.

Calling Sig

Result type is always floating (auto-deduced), arg type is auto-deduced

constexpr auto result = esv::cos(value);

Result type is explicit set, arg type is auto-deduced

constexpr auto result = esv::cos.fn<result_type>(value);

Result type is explicit set, arg type is explicit set

constexpr auto result = esv::cos.fn<result_type, arg_type>(value);

Note

	Note
	The returned float type is one of esv::f32, esv::f64, esv::f128, esv::fmax, esv::fx32, esv::fx64, esv::fx128, esv::fxmax. constexpr support.
