Daily Lesson (3/75) arithmetic operation instruction

Arithmetic Operation commands are commands that reflect the computing power of the CPU. They are also the most commonly used commands in programming, including addition, subtraction, multiplication, division, and other auxiliary commands. The operand of this group of commands can be 8-bit, 16-bit, 32-bit (80386 +). When the storage unit is the operand of this class of commands, the addressing method of this operand can be the addressing method of any storage unit. 1. Addition commandAdd RE

Javascript calculates the distance between two points on the earth based on the longitude and latitude.

There is a problem only when dealing with the relative points on the sphere, and there is a correction formula, because there is no need to find it, it can be found on the Wiki. Of course, we all know that the earth is not a real sphere, but an elliptical sphere, so we have the following formula: /** * approx distance between two points on earth ellipsoid * @param {Object} lat1 * @param {Object} lng1 * @param {Object} lat2 * @param {
