shz::sincos

C++ sine/cosine approximation pairs.

This structure contains the precomputed values for both sine and cosine of an angle.

• Header: #include <sh4zam/shz_trig.hpp> (source)
• C type: shz_sincos_t (layout-compatible; the C API accepts it directly)
• Bases: shz_sincos_t

Static functions

from_radians

static sincos from_radians(float rad) noexcept
static sincos from_radians(uint16_t rad) noexcept

Returns a new sin/cos pair from the given angle in radians.

Calls: shz_sincosf(), shz_sincosu16()

from_degrees

static sincos from_degrees(float deg) noexcept

Returns a new sin/cos pair from the given angle in degrees.

Calls: shz_sincosf_deg()
