Limiting floats to two decimal points
To limit a float to two decimal points, you can use the round()
function. This function will round a number to a specified number of decimal places.
Here is an example:
This will print 3.14
, as y
has been rounded to two decimal places.
You can also use the format()
function to achieve the same result. This function returns a string representation of a number. You can use the :.2f
format specifier to specify that you want a float with two decimal places.
Here is an example:
This will also print 3.14
.
If you want to actually change the value of the float itself, rather than just printing it, you can use either of these approaches in an assignment statement. For example:
or
This will change the value of x
to 3.14
