CRegistry:GetNum

The GetNum method returns a numeric value form a registry key. The method also specifies a default value to be returned if the named value or key does not already exist in the Registry.

Syntax

nValue = CRegistry:GetNum( sName, nDefault )

  • nValue is a numeric value returned as a real number.
  • sName is the name of the value to fetch.
  • nDefault is the default numeric value returned if sName is not found in the Registry.

Example

The following script opens a key specified by sKeyName and returns a numeric value saved under the name "MyVal":

 

R = CRegistry:Open( sKeyName )

-- open the key and create a CRegistry object

v = R:GetNum( "MyVal", 16.25 )

-- fetch the value of "MyVal", default to 16.25

Printf( "MyVal= %lg", v )

-- Result: MyVal= 12.484 (value already existed)
