 An integer type is a range constrained field type. The Noir frontend supports arbitrarily-sized, both unsigned and signed integer types.
 
-> **Note:** When an integer is defined in Noir without a specific type, it will default to `Field`. The one exception is for loop indices which default to `u64` since comparisons on `Field`s are not possible.

 The bit size determines the maximum and minimum range of value the integer type can store. For example, an `i8` variable can store a value in the range of -128 to 127 (i.e. $\\-2^{7}\\$ to $\\2^{7}-1\\$).
