floorEps()

divideEps()

double QwtScaleArithmetic::divideEps ( double  intervalSize, double  numSteps  )

static

Divide with epsilon tolerance

Divide an interval into steps

Formula:

参数

intervalSize	Interval size
numSteps	Number of steps

返回

Step size

divideInterval()

double QwtScaleArithmetic::divideInterval ( double  intervalSize, int  numSteps, uint  base  )

static

Divide interval

Calculate a step size for a given interval

参数

intervalSize	Interval size
numSteps	Number of steps
base	Base for the division (usually 10)

返回

Calculated step size

floorEps()

double QwtScaleArithmetic::floorEps ( double  value, double  intervalSize  )

static

Floor with epsilon tolerance
