Mathematical Functions

Data scientists frequently want to find anomalies in numerical data. To that end, HCP has some mathematical functions.

Table 1. Mathematical Functions
Function Description Input Returns
ABS Returns the absolute value of a number.
  • number - The number to take the absolute value of

The absolute value of the number passed in
BIN Computes the bin that the value is in given a set of bounds
  • value -the value to bin

  • bounds - A list of value bounds (excluding min and max) in sorted order

Which bin N the value falls in such that bound(N-1) < value <= bound(N). No min and max bounds are provided, so values smaller than the 0'th bound go in the 0'th bin, and values greater than the last bound go in the M'th bin.
