Numbers
The number controls allow the user to enter numerical data associated with a line. The numerical data is expressed as signed integers, unsigned integers, or integer decibel values. These controls use the MIXERCONTROLDETAILS_SIGNED and MIXERCONTROLDETAILS_UNSIGNED structures to retrieve and set control properties. The following table describes the types of number controls.
| Control | Description |
| Signed | Allows integer values entered in the range of - 231 through (231 - 1). |
| Unsigned | Allows integer values entered in the range of 0 through (232 - 1). |
| Decibel | Allows integer decibel values to be entered, in tenths of decibels. The range of values for this control is - 32,768 through 32,767. |
| Percent | Allows values to be entered as percentages. |
