Variable c_pi¶
variable c_pi simd¶
template <typename T, int m = 1, int d = 1>
constexpr inline subtype<T> c_pi = subtype<T>(3.1415926535897932384626433832795 * m / d)The mathematical constant π (pi), scaled by m/d.
| T | The numeric type. |
| m | Numerator multiplier (default is 1). |
| d | Denominator divisor (default is 1). |
Note
Examples: - c_pi<f64, 4> = 4π - c_pi<f64, 3, 4> = 3/4π
