Aspects

Floating-point

Floating point numbers are approximations of real numbers that can represent larger ranges than integers but use the same amount of memory, at the cost of lower precision

"The floating-point numbers are rounded to have not more than eight fractions digits" from question "Batch extract numbers between quotes, multiply and write back" "All other fractions floats have more digits after the dot when expressed in decimal because the representation of floating-point numbers is binary not decimal" from question "Division of Float's not accurate in Swift" |

Values more realistic |
"And using floating-point values is more realistic - you need fractions values because when you rotate something the new coordinates will nearly always be non integral" from question "What values to use in my 3D-space" |
