Function acosh [src]

Returns the hyperbolic arc-cosine of x. Special cases: acosh(x) = nan if x < 1 acosh(nan) = nan

Prototype

pub fn acosh(x: anytype) @TypeOf(x)

Example

 test acosh {
    try expect(acosh(@as(f32, 1.5)) == acosh32(1.5));
    try expect(acosh(@as(f64, 1.5)) == acosh64(1.5));
}

Source

  pub fn acosh(x: anytype) @TypeOf(x) {
    const T = @TypeOf(x);
    return switch (T) {
        f32 => acosh32(x),
        f64 => acosh64(x),
        else => @compileError("acosh not implemented for " ++ @typeName(T)),
    };
}
