## Function Documentation

 qreal qAcos ( qreal v )
inline

Returns the arccosine of v as an angle in radians. Arccosine is the inverse operation of cosine.

qAtan(), qAsin(), qCos()
 qreal qAsin ( qreal v )
inline

Returns the arcsine of v as an angle in radians. Arcsine is the inverse operation of sine.

See also
qSin(), qAtan(), qAcos()
 qreal qAtan ( qreal v )
inline

Returns the arctangent of v as an angle in radians. Arctangent is the inverse operation of tangent.

 qreal qAtan2 ( qreal y, qreal x )
inline

Returns the arctangent of a point specified by the coordinates y and x. This function will return the angle (argument) of that point.

See also
qAtan()
 int qCeil ( qreal v )
inline

Return the ceiling of the value v.

The ceiling is the smallest integer that is not less than v. For example, if v is 41.2, then the ceiling is 42.

qFloor()
 qreal qCos ( qreal v )
inline

Returns the cosine of an angle v in radians.

See also
qSin(), qTan()
 qreal qExp ( qreal v )
inline

Returns the exponential function of e to the power of v.

See also
qLn()
 int qFloor ( qreal v )
inline

Return the floor of the value v.

The floor is the largest integer that is not greater than v. For example, if v is 41.2, then the floor is 41.

See also
qCeil()
 qreal qLn ( qreal v )
inline

Returns the natural logarithm of v. Natural logarithm uses base e.

See also
qExp()
 qreal qPow ( qreal x, qreal y )
inline

Returns the value of x raised to the power of y. That is, x is the base and y is the exponent.

See also
qSqrt
 qreal qSin ( qreal v )
inline

Returns the sine of the angle v in radians.

See also
qCos(), qTan()
 qreal qSqrt ( qreal v )
inline

Returns the square root of v. This function returns a NaN if v is a negative number.

See also
qPow()
 qreal qTan ( qreal v )
inline

Returns the tangent of an angle v in radians.
