This code gives us the right answer of 9. print (27*3/9) So I thought, oh that's integer multiplication followed by division, that's why it's accurate. But nope ... WebNov 16, 2024 · The float type in Python represents the floating point number. Float is used to represent real numbers and is written with a decimal point dividing the integer and fractional parts. For example, 97.98, 32.3+e18, -32.54e100 all are floating point numbers. Python float values are represented as 64-bit double-precision values.
