Function Documentation

◆ FastRTS_cosf()

float FastRTS_cosf ( const float  theta)

The Cosine Function.

Parameters
[in]theta- Angle in radians
Returns
The cosine of the angle

◆ FastRTS_sinf()

float FastRTS_sinf ( const float  theta)

The Sine Function.

Parameters
[in]theta- Angle in radians
Returns
The sine of the angle

◆ FastRTS_sincos()

void FastRTS_sincos ( const float  theta,
float *  retValues 
)

The Sine/Cosine Function.

Parameters
[in]theta- Angle in radians
[in]retValues- pointer that stores return sine and cosine values

◆ FastRTS_acosf()

float FastRTS_acosf ( const float  theta)

The Arccosine Function.

Parameters
[in]theta- Angle in radians
Returns
The cosine of the angle

◆ FastRTS_asinf()

float FastRTS_asinf ( const float  theta)

The Arcsine Function.

Parameters
[in]theta- Angle in radians
Returns
The sine of the angle

◆ FastRTS_atanf()

float FastRTS_atanf ( const float  x)

The Arctangent function.

Parameters
[in]xthe arc subtended by the angle theta
Returns
theta , the angle subtended by the arc of length x

◆ FastRTS_atan2f()

float FastRTS_atan2f ( const float  y,
const float  x 
)

The Arctangent(y,x) function.

Parameters
[in]y- numerator of the ratio y/x which is the length of the arc subtended by the angle theta
[in]x- denominator of the ratio y/x which is the length of the arc subtended by the angle theta
Returns
theta , the angle subtended by the arc of length y/x

◆ FastRTS_expf()

float FastRTS_expf ( const float  x)

The Exponent function.

Parameters
[in]x- argument whose exponent is to be calculated
Note
due to the allowable range of 32-bit float, the maximum exponent allowed is +/-88
Returns
e^x , the exponent of the argument

◆ FastRTS_logf()

float FastRTS_logf ( const float  x)

The Natural Logarithm function.

Parameters
[in]x- argument whose logarithm is to be calculated
Returns
log(x) , the natural logarithm of the argument
