Function cosh [src]

Returns the hyperbolic cosine of x. Special Cases: cosh(+-0) = 1 cosh(+-inf) = +inf cosh(nan) = nan

Prototype

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

Example

 test cosh {
    try expect(cosh(@as(f32, 1.5)) == cosh32(1.5));
    try expect(cosh(@as(f64, 1.5)) == cosh64(1.5));
}

Source

  pub fn cosh(x: anytype) @TypeOf(x) {
    const T = @TypeOf(x);
    return switch (T) {
        f32 => cosh32(x),
        f64 => cosh64(x),
        else => @compileError("cosh not implemented for " ++ @typeName(T)),
    };
}
