Why does

x = int(34.43)
y = int('72')
z = float('22.43')

give x = 34, y= 72 and z = 22.43

but

x = int('10.8')

result in an error, and not x = 10

Does it have something to do with how float values are stored in memory? Any detailed explanations as to why this happens are most welcome (not how to resolve this issue). Thanks in advance

  • install the try parse library https://pypi.org/project/try-parse/ then check if the string can be parse as an integer – Golden Lion Jan 13 '21 at 16:44
  • you can't convert a float in a string to an int base 10 directly. You can use the type to determine if the string is int or float then cast accordingly. https://stackoverflow.com/questions/379906/how-do-i-parse-a-string-to-a-float-or-int – Golden Lion Jan 13 '21 at 16:47
  • x=round(float("10.8"),0) print(x) if your not downcasting otherwise x=int(float("10.8")) https://www.java67.com/2015/10/how-to-convert-float-to-int-in-java-example.html – Golden Lion Jan 13 '21 at 16:51
