/**
 * Searches for a place for a float number (x) in an array of float numbers (arr) sorted in ascending order.
 * Returns an array of 3 indices:
 [
 <index of nearest smaller number | null>,
 <index of number equal to desired | null>,
 <index of nearest larger number | null>
 ]
 Numbers are compared using SIGMA: if the numbers differ by less than SIGMA, then they are considered equal.
