Function Documentation

radians()

double radians ( double a )

constexpr

Convert degrees to radians.

Parameters

a	Angle in degrees.

degrees()

double degrees ( double a )

constexpr

Convert radians to degrees.

Parameters

a	Angle in radians.

smoothstep()

double smoothstep ( double edge0, double edge1, double a )

constexpr

Performs smooth Hermite interpolation between 0 and 1 when edge0 < x < edge1.

Parameters

edge0	Specifies the value of the lower edge of the Hermite function.
edge1	Specifies the value of the upper edge of the Hermite function.
a	Specifies the source value for interpolation.

sind()

double sind ( double x )

inline

Sine function where multiples of 90 degrees come out exact.

Parameters

x	Angle in degrees.

cosd()

double cosd ( double x )

inline

Cosine function where multiples of 90 degrees come out exact.

Parameters

x	Angle in degrees.
