# Fixed-point number

In programming, a fixed-point number is used to represent a number with a **fractional part** that has a **fixed precision**.

The term *'fixed-point'* comes from the fact that the decimal point always remains fixed at a particular position in the number's internal representation. This is contrary to how a ** floating-point number** works, wherein the decimal point keeps changing its position depending on the mantissa and exponent values.
