I know how to control the number of decimals, but how do I control the number of zeros specifically?
For example:
104.06250000 -> 104.0625
119.00000 -> 119.0
72.000000 -> 72.0
899
To format floats without trailing zeros with Python, we can use the rstrip method. We interpolate x into a string and then call rstrip with 0 and '. ' to remove trailing zeroes from the number strings. Therefore, n is 3.14.
We can print the double value using both %f and %lf format specifier because printf treats both float and double are same. So, we can use both %f and %lf to print a double value.
Use the format() function to add zeros to a float after the decimal, e.g. result = format(my_float, '. 3f') . The function will format the number with exactly N digits following the decimal point.
You can do: printf("%. 2lf\n", F); printf("%. 3lf\n", F); printf("%.
How about using the decimal module?
From the documentation:
"The decimal module incorporates a notion of significant places so that 1.30 + 1.20 is 2.50. The trailing zero is kept to indicate significance. This is the customary presentation for monetary applications. For multiplication, the “schoolbook” approach uses all the figures in the multiplicands. For instance, 1.3 * 1.2 gives 1.56 while 1.30 * 1.20 gives 1.5600."
The normalize() function removes trailing zeros:
>>> from decimal import *
>>> d1 = Decimal("1.30")
>>> d2 = Decimal("1.20")
>>> d3
Decimal("1.5600")
>>> d3.normalize()
Decimal("1.56")
