Scaling of Units from double to float-CodePudding

Below is my output and the value is represented in scaled units like below.

Default value: 2.000000e-02

When ever the value is represented as double(like above), I would like to convert and print like a floating value(0.02) Expected Output Default value: 0.02

Could anyone pls help me with this?

Format strings are the correct choice for this task I think. The .2f specifies that the number should be converted into fixed-point notation and have exactly two digits after the decimal point. Example:

d = 2.000000e-02
print("{:.2f}".format(d))

Output:

0.02

What you are looking for is called string formatting. % and .format are used for this task, pyformat.info has explanation and comparison of boths. In this case you might easily use either, that is to get 2 digits after . you might do

x = 2.000000e-02
print('%.2f' % x)  # 0.02
print('{:.2f}'.format(x))  # 0.02

Alternatively you might use so-called f-strings (requires python3.6 or newer) that is

x = 2.000000e-02
print(f'{x:.2f}')  # 0.02

Consult your organization style guidelines to detect which one you should use.
