Function std.complex.expi

Calculates cos(y) + i sin(y).

Prototype

Complex!(real) expi(
  real y
) pure nothrow @nogc @trusted;

Note

expi is included here for convenience and for easy migration of code that uses std.math.expi. Unlike std.math.expi, which uses the x87 fsincos instruction when possible, this function is no faster than calculating cos(y) and sin(y) separately.
