QwtScaleArithmetic(3)

Hey bestie 💖 this is QwtScaleArithmetic(3), straight outta the Library Functions Manual, and it’s here to make tolerance arithmetic make sense. No cap.

🌸 NAME 🌸

QwtScaleArithmetic - Arithmetic including a tolerance. Periodt. ✨

🎀 SYNOPSIS 🎀

#include <qwt_scale_engine.h>

🦋 Static Public Member Functions 🦋

• static double ceilEps (double value, double intervalSize) — static public member function vibes.
• static double floorEps (double value, double intervalSize) — static public member function vibes.
• static double divideEps (double intervalSize, double numSteps) — Divide an interval into steps.
• static double divideInterval (double intervalSize, int numSteps, uint base) — static public member function vibes.

💜 Detailed Description 💜

Arithmetic including a tolerance. That’s the whole concept, and honestly? Iconic. 💅

💖 Member Function Documentation 💖

🌟 double QwtScaleArithmetic::ceilEps (double value, double intervalSize) 🌟

[static]

Ceil a value, relative to an interval.

Parameters:

• value — Value to be ceiled
• intervalSize — Interval size

Returns: Rounded value

See also: floorEps()

Definition at line 108 of file qwt_scale_engine.cpp.

---

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

[static]

Divide an interval into steps. The formula is literally:

$stepSize = (intervalSize - intervalSize
       * 10e^{-6}) / numSteps$

Parameters:

• intervalSize — Interval size
• numSteps — Number of steps

Returns: Step size

Definition at line 143 of file qwt_scale_engine.cpp.

---

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

[static]

Calculate a step size for a given interval.

Parameters:

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

Returns: Calculated step size

Definition at line 160 of file qwt_scale_engine.cpp.

---

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

[static]

Floor a value, relative to an interval.

Parameters:

• value — Value to be floored
• intervalSize — Interval size

Returns: Rounded value

See also: floorEps() — yes, same name, preserved exactly 💀

Definition at line 126 of file qwt_scale_engine.cpp.
