[This documentation is for preview only, and is subject to change in later releases. Blank topics are included as placeholders.]

Gets or sets the number of digits in each group to the left of the decimal in numeric values.

**Namespace:**System.Globalization

**Assembly:**mscorlib (in mscorlib.dll)

Every element in the one-dimensional array must be an integer from 1 through 9. The last element can be 0.

The first element of the array defines the number of elements in the least significant group of digits immediately to the left of the NumberDecimalSeparator. Each subsequent element refers to the next significant group of digits to the left of the previous group. If the last element of the array is not 0, the remaining digits are grouped based on the last element of the array. If the last element is 0, the remaining digits are not grouped.

For example, if the array contains { 3, 4, 5 }, the digits are grouped similar to "55,55555,55555,55555,4444,333.00". If the array contains { 3, 4, 0 }, the digits are grouped similar to "55555555555555555,4444,333.00".
