Swift Float
Main Idea
A basic data type that holds a floating point number. Float -> Double(double-precision floating-point number)
// How to store decimal numbers, the decimal point floats
// Decimals can cause problems
// 0.1 + 0.3 = 0.30000000000000004 – that 0.3,
// 1 + 2.0 cannot add int and double b./c we want only small error not but one.
// Name = “nick”
// Name = 57 NONONO, cannot change
// Resolve Decimal rounding issues using ints

let floatNum = Double(0.1)
let floatNum2 = Double(0.2)
print(round(((floatNum + floatNum2) * 10)) / 10)
