Median med

The median is the middle value of a dataset. It is the value that separates the higher half from the lower half of the data. Always returns a float value.

Notes

• If the dataset has an odd number of values, the median is the middle value
• If the dataset has an even number of values, the median is the average of the two middle values
• Always returns float, even for integer inputs
• Returns 0Nf (null float) for empty vectors or null inputs
