ratio(\)
Syntax
X \ Y
Arguments
X and Y is a scalar/pair/vector/matrix. If X or Y is a pair/vector/matrix, the other is a scalar or a pair/vector/matrix of the same size.
Details
Return element-by-element ratio of X to Y. Function ratio
always returns floating numbers. If both X and Y are integer/long, ratio
( converts them into floating numbers and then conduct division. This is different from operator div (/), which does not convert integer/long to floating numbers. Another difference with div
is that Y can be negative integers when X is integer.
