A numeric keypad, also known as a number pad or a numeric keyboard, is a specialized layout of keys or buttons designed to input numerical characters, mathematical symbols, and some auxiliary functions into a computer or electronic device. It serves as a separate section or an integrated part of a keyboard, typically situated to the right of the alphanumeric keys.
The numeric keypad usually consists of a grid-like arrangement of keys, ranging from 0 to 9, organized in the same manner as a traditional calculator. Apart from these numeric characters, it also includes additional function keys such as arithmetic operators like +, -, *, /, and other symbols like decimal point (.), parentheses (), enter key, and the equal sign (=).
The primary purpose of a numeric keypad is to facilitate quick and efficient input of numerical data, especially when dealing with tasks involving calculations, data entry, accounting software, financial calculations, or other numerical operations. It enables users to perform calculations or enter numerical values with ease and speed, without relying solely on the number keys located across the top of the alphanumeric keyboard.
Numeric keypads are commonly found on desktop keyboards, but they are also available as standalone devices or as integrated components on laptops, calculators, cash registers, and other specialized systems. Their ergonomic design and distinct layout offer convenience and streamline numerical input, enhancing productivity and accuracy when working with numerical data.
The word "numeric keypad" consists of two main components: "numeric" and "keypad".
The term "numeric" is derived from the Latin word "numerus", meaning "number". It refers to anything related to numbers or numerical values.
The word "keypad" is a combination of "key" and "pad". "Key" comes from Middle English "kei", which originated from the Old English word "cǣg" meaning "metal piece; wedge". "Pad" has its roots in the Middle English word "padde", which referred to a cushion or soft covering.
Therefore, the term "numeric keypad" essentially refers to a set of keys used specifically for numeric input, like the arrangement of numbers on a telephone keypad or calculator.
