double __divf32( double num , double denom ); DIVF32 dst, num, denom Return num divided by denom using the TMU
hardware instruction for floating point division.
double __sqrt( double src ); SQRTF32 dst, src Return the square root of src.
double __sin( double src ); SINF32 dst, src Return the sine of src radians, where src is
provided in radians.
double __cos( double src ); COSF32 dst, src Return the cosine of src radians, where src is
provided in radians.
double __atan( double src ); ATANF32 dst, src Return the principal value of the arc tangent of
src radians.
double __atan2( double y , double x ); QUADF32 quadrant, ratio, y, x Return the principal value of the arc tangent
ATANPUF32 atanpu, ratio plus the quadrant for x, y. The value is returned
ADDF32 atan2pu, atanpu in radians.
MPY2PIF32 atan2, atan2pu
double __mpy2pif32( double src ); MPY2PIF32 dst, src Return the result of multiplying src by 2pi. This
converts a per unit value to radians. Per unit
values are commonly used in control
applications to represent normalized radians.
double __div2pif32( double src ); DIV2PIF32 dst, src Return the result of multiplying src by 1/2pi
(effectively dividing by 2pi). This converts a
value in radians to a per unit value.
double __sinpuf32( double src ); SINPUF32 dst, src Return the sine of src in radians, where src is
provided as a per unit value.
double __cospuf32( double src ); COSPUF32 dst, src Return the cosine of src in radians, where src is
provided as a per unit value.
double __atanpuf32( double src ); ATANPUF32 dst, src Return the principal value of the arc tangent of
src, which is provided as a per unit value.
double __atan2puf32( double x, double y ); QUADF32 quadrant, ratio, y, x Return the principal value of the arc tangent
ATANPUF32 atanpu, ratio plus the quadrant value for y, x. The value is
ADDF32 dst, atanpu returned as a per unit value.
double __quadf32( double ratio, double y, QUADF32 quadrant, ratio, y, x Return the quadrant value (0.0, +/-0.25, or +/-
double x ); 0.5) and the ratio of x and y, which are
provided as per unit values.
