Description

Store a single Luau number, defined to be double-precision floating point number, or more commonly known as a double. This stores a number in 64 bits (8 bytes) using the IEEE 754 representation (1 sign bit, 11 exponent bits and 52 fractional bits). Maximum and minimum values are ±1.7976931348623157e+308, with a range of ±2^53 for exact integer representations.

Like all ValueBase objects, this single value is stored in the Value property. The Changed event fires with the new value being stored in the object, instead of a string representing the property being changed.

Changed

Parameters (1)
valuedouble

Fires whenever the NumberValue.Value changes. It runs with the new value being stored in the argument object, instead of a string representing the property being changed.

Listening for the Changed signal can be useful in games that use NumberValues to track values like leaderboard statistics or item prices.
