PyQt5 QDoubleSpinBox – Getting Decimal Precision

In this article we will see how we can get the decimal precision of the QDoubleSpinBox. By default decimal precision of double spin box is 2 although we can change it any time with the help of setDecimals method. Decimal precision is the number of digits to the right of the decimal point in a number. For example, the number 123.45 has a decimal precision of 2.

In order to do this we will use decimals method with the double spin box object.

Syntax : dd_spin.decimals()

Argument : It takes no argument

Return : It returns integer

Below is the implementation

# importing libraries

import sys


class Window(QMainWindow):

    def __init__(self):
        super().__init__()

        # setting title
        self.setWindowTitle("Python ")

        # setting geometry
        self.setGeometry(100, 100, 500, 400)

        # calling method
        self.UiComponents()

        # showing all the widgets
        self.show()

    # method for components
    def UiComponents(self):

        # creating double spin box
        d_spin = QDoubleSpinBox(self)

        # setting geometry to the double spin box
        d_spin.setGeometry(100, 100, 150, 40)

        # setting decimal precision
        d_spin.setDecimals(4)

        # step type
        step_type = QAbstractSpinBox.AdaptiveDecimalStepType

        # adaptive step type
        d_spin.setStepType(step_type)

        # creating a label
        label = QLabel("GeeksforGeeks", self)

        # setting geometry to the label
        label.setGeometry(100, 200, 300, 80)

        # making label multi line
        label.setWordWrap(True)

        # getting decimal precision
        value = d_spin.decimals()

        # setting text to the label
        label.setText("Decimal Precision : " + str(value))





# create pyqt5 app
App = QApplication(sys.argv)

# create the instance of our Window
window = Window()

# start the app
sys.exit(App.exec())

Output :
