Function Documentation

bool fuzzyCompare ( double  a,
double  b 
) [inline]

Tests if two double values are nearly equal.

Returns:
true if the two double numbers are equal in terms of the machine precision, which means their difference must be less than 1E-11.

Definition at line 28 of file MathToolbox.hpp.

bool fuzzyCompare ( float  a,
float  b 
) [inline]

Tests if two float values are nearly equal.

Returns:
true if the two float numbers are equal in terms of the machine precision, which means their difference must be less than 1E-6.

Definition at line 47 of file MathToolbox.hpp.

double hypot ( double  x,
double  y,
double  z 
)

template<typename floatT >
bool isNaN ( floatT  x) [inline]

Checks if a floating point value is Not-a-Number (NaN)

The floating-point standard IEC 559 (a.k.a. IEEE 754) specifies that a floating-point value x represents NaN if x != x.

NaN, NaN_double, http://en.wikipedia.org/wiki/IEC_559

double normalizeRadians ( double  radians)

Normalizes an angle given in radians by adding or subtracting an integer multiple of 2*pi so that the resulting angle is in the half-open interval [-pi,+pi). The current implementation takes O(1) time, i.e. the time of execution has a fixed upper boundary independend from the angle.

template<typename IntT >
IntT round_to_int ( float  floatValue) [inline]

Round to the closest integer.

Parameters:
floatValueThe float value that shall be rounded
Returns:
floatValue rounded to the closest integer

Definition at line 74 of file MathToolbox.hpp.

template<typename IntT >
IntT round_to_int ( double  floatValue) [inline]

Round to the closest integer.

Parameters:
floatValueThe float value that shall be rounded
Returns:
floatValue rounded to the closest integer

Definition at line 88 of file MathToolbox.hpp.

double sqr ( double  val) [inline]

Definition at line 36 of file MathToolbox.hpp.
