Perform the ‘distance’ formula using floating point math. The distance formula is typically used to find the distance between two points and is:

dist = sqrt( (x1 - x2)^2 + (y1 - y2)^2 )

The math is done internally using floating point math to minimize roundoff. The end result is then rounded to the nearest integer.

#### Params

x1 | x coordinate of first point |

y1 | y coordinate of first point |

x2 | x coordinate of second point |

y2 | y coordinate of second point |

#### Returns

The closest integer value after peforming the distance formula.
