Floats

Floats are similar to integers, but they can also include decimal fractions. Float means that the numbers always have a decimal part separated by a dot. The number of decimals is also called precision, e.g.

• 5.8656345
• -332.8463463463753646

Normally you do not need very high precisions for your calculations and two or three decimals will be enough in 99% of all cases. Floats and integers can be used together and the result is always a floating number:

value1 = 5
value2 = 3.6222
result = value1 - value2

scene.message(str(result))

If an instruction expects a floating number and you want to enter a value of exactly 2, for example, then you really have to type in a floating number, not an integer:

getNeighbors(2.0)

Floating numbers can be translated into integers and vice versa, but there might be a problem with precision, because the decimals will be truncated, leaving only the integer part:

int(7.57634) = 7 or int(6.99999) = 6
float(3) = 3.0
