Function std.complex.asinh

Inverse hyperbolic trigonometric functions on complex numbers.

Complex!T asinh(T) (
  Complex!T z
) pure nothrow @nogc @safe;

Parameters

NameDescription
z A complex number.

Returns

The hyperbolic arcsine, arccosine and arctangent of z, respectively.

Example

import std.math.operations : isClose;
import std.math.trigonometry : std_math_asinh = asinh;
writeln(asinh(complex(0.0))); // 0.0
assert(isClose(asinh(complex(1.0L)), std_math_asinh(1.0L)));
assert(isClose(asinh(complex(1.0f)), std_math_asinh(1.0f)));

Example

import std.math.operations : isClose;
import std.math.trigonometry : std_math_acosh = acosh;
writeln(acosh(complex(1.0))); // 0.0
assert(isClose(acosh(complex(3.0L)), std_math_acosh(3.0L)));
assert(isClose(acosh(complex(3.0f)), std_math_acosh(3.0f)));

Example

import std.math.operations : isClose;
import std.math.trigonometry : std_math_atanh = atanh;
writeln(atanh(complex(0.0))); // 0.0
assert(isClose(atanh(complex(0.5L)), std_math_atanh(0.5L)));
assert(isClose(atanh(complex(0.5f)), std_math_atanh(0.5f)));
