Adding and Subtracting a number. float (floating point real values) − Also called floats, they represent real numbers and are written with a decimal point dividing the integer and the fractional parts. But due to python being dynamically typed language, you can use float(inf) as an integer to represent it as infinity. Represent infinity as an integer in Python 2.7 . Like many complex mathematical equations and results, infinity in Python has its own caveats that you need to be aware of: Though most basic math functions in a Python object will not deal with infinite or negative infinite results, when you do work with infinity and negative infinity, you can still get NaN results. Positive infinity number is greatest, and the negative infinity number is the smallest of all numbers. Upper limit of integration (use numpy.inf for +infinity). Sauf si, bien sûr, comme indiqué, x est également l'infini ou "nan" ("pas un nombre"). The negative float value gives the negative integer on conversion. 1.
