Float is a variable that represents the real numbers. That is, values where we have 1.7, 2.8, 2.5... among others.

In the above case, the variable is float because it is a value in kgs for the user to put their weight.

Some time ago I created a Python application to perform the calculation of the IMC, where the user put his weight and height and the program printed on the screen his IMC.

  • Actually I’m also trying to develop an IMC calculator, thank you ;)

    Correcting the nomenclature: float is a native class of the language to work with floating point.

  • I agree with Anderson’s answer, just remembering that floating point, are fractional numbers that in mathematics belong to the set of real numbers. If you need an example, I found a script for a Python IMC calculation program: https://www.portugal-a-programar.pt/forums/topic/72919-calculator-de-imc/ I hope I helped. Hug!

input takes a user keyboard input, and returns a string.

'1.5' would be the representation of a kilo and a half, but it is in quotes, characterizing a string, and if this value is used in a mathematical calculation will occur an error.

Now passing this string in the function float, causes it to be converted to floating number and thus the mathematical calculation becomes possible.

Numbers with a decimal point belong to a type called float, because these numbers are represented in a format called floating point
