Let’s consider you want to convert a floating point number into an integer. There are two ways of doing that.
Method 1 – Truncating
You can truncate the floating point number to just the portion before the decimal point. You can do that with the
int() function which truncates the number towards zero.
>>> fpn = 57.83 >>> int(fpn) 57
Alternatively, there is a function that will truncate floating point numbers to only the integer part. It is part of the
math module and it is called
>>> import math >>> fpn = 57.83 >>> math.trunc(fpn) 57
math.trunc() truncate floating point numbers to only the integer part.
Method 2 – Rounding
You can round the floating point number to the nearest integer. So, what about this one:
>>> fpn = 57.83 >>> round(fpn) 58.0 >>> int(round(fpn)) 58
You can round to only one decimal place for example, using the
>>> fpn = 57.83 >>> round(fpn, 1) 57.8
You can also convert floating point numbers to integers and round them up or down using the
>>> import math >>> fpn = 57.83 >>> int(math.floor(fpn)) 57 >>> int(math.ceil(fpn)) 58
