# point (1-point.org)

A point is a sharp tip, like a needle or a pencil. It is also a single idea or fact, or a place on a map. In sports, it is one unit of score.

## What a model may hear
- floating-point number (computer science and programming): treat the word as a numeric data type with decimal places, not a whole number
- pointer (programming in C, C++, and similar languages): read it as a memory address or reference to data, and may write code using pointer arithmetic
- data point (machine learning and statistics): interpret it as one observation in a dataset, a single row of features and labels
- point in geometry (mathematics and graphics): understand it as a zero-dimensional location in space, often with x and y coordinates
- point of presence (networking and telecom): see it as a physical access location or edge node in a network

## Where people and models part ways
- Says: "make your point"
  Means: be clear and convincing
  May be taken as: generate code for creating or manipulating a data point
  Say instead: "state your argument clearly"
- Says: "what is the point"
  Means: why does this matter
  May be taken as: explain geometric points or return the value of a pointer
  Say instead: "why does this matter or what is the purpose"
- Says: "point me to the file"
  Means: show where the file is
  May be taken as: return a memory pointer or write code using pointer syntax
  Say instead: "show me where the file is located"
- Says: "two point five"
  Means: the number 2.5
  May be taken as: interpret as two separate integers or as pointer notation
  Say instead: "the number 2.5 or two and a half"

## Tips
- say 'decimal number' or 'floating point' when you mean a number with digits after the dot
- say 'show me' or 'direct me to' instead of 'point me to' when giving locations
- say 'main idea' or 'purpose' instead of 'point' when discussing meaning
- say 'score' or 'tally' in sports contexts to avoid numeric type confusion
- specify 'memory address' or 'reference' if you actually want pointer behavior

## Often confused with
- dot: a dot is the mark itself, not the concept or location
- tip: a tip is only the physical end, not an idea or score
- pointer: a pointer is specifically a programming reference, not a general indication
- vertex: a vertex is where lines meet, not a standalone location or idea
- node: a node is a connected element in a network or tree, not a free point
