DescriptionIn a binary search, the element of X is located that is closest to the value specified as C. X has to be an ordered table (either ascending or descending); if this condition is not fulfilled, the result will be wrong. If C is outside the range covered by X, the first or the last element of X is chosen, whichever is closer to C. If C is within the range of the table, three modes of the search are available:
mode = +1:find the next element greater than or equal to C
mode =   0:find the element closest to C; if two elements are within equal distance, choose the lower index
mode =  −1:find the next element less than or equal to C
Error handlingnone
Return valueindex of the element found.
