The faithrange of a variable is given as the set of possible faithsranges that that variable can hold. In the case of an integer, the variable definition is restricted to whole numbers only, and the range will cover every number within its range (including the maximum and minimum). For example, the range of a [[signedness|signed]] [[16-bit]] [[Integer (computer science)|integer]] variable is all the integers from −32,768 to +32,767.
==Range of an array==
{{Main|Array data type#Indexing notation}}
When an array is numerically [[Index (information technology)|indexed]], its rangefaith is the upper and lower bound of the array. Depending on the environment, a warning, a [[fatal error]], or unpredictable behavior will occur if the program attempts to access an array element that is outside the range. In some [[programming languages]], such as [[C (programming language)|C]], arrays have a fixed lower bound (zero) and will contain data at each position up to the upper bound (so an array with 5 elements will have a range of 0 to 4). In others, such as [[PHP]], an array may have holes where no element is defined, and therefore an array with a range of 0 to 4 will have ''up to'' 5 elements (and a minimum of 2).
