Mathematical constant
From the Simple English Wikipedia, the free encyclopedia that anyone can change
A mathematical constant is a number, which has a special meaning for calculations. For example, the constant π (spoken as "pi") means the ratio of the length of a circle's circumference to its diameter. This value is always the same for any circle. In contrast to physical constants, mathematical constants do not come from physical measurements.
