CDbl - method of object Pm

Returns an expression converted into the Double type.
CDbl(value As Double) As Double
n = Pm.CDbl(value)
value(Double) Any valid numeric expression.

The conversion functions can be used e.g. if you want some operation result to be expressed as a particular data type (rather than the default data type). For example, use CDbl or CSng method to force the Double or Single data type in cases where integer arithmetic normally would occur.

Use this method to provide conversion independent on local system settings from any other data type to the Double type. Conversion of string value where the decimal separator is "period" or "comma", will be completed correctly in both cases. depending on the locale setting of your system. Compare with VBScript.CDbl.

If it is needed to convert the real number into the String type regardless on local setting of OS Windows (i.e. the real number would always have "full stop" or "comma" as a decimal separator), then the Pm.TransformValue method can be used with parameter nType = 120, 121 or 122.
The method can also be called in the graphic item events for Web panels.
Dim n1, n2
n1 = Pm.CDbl("3.14")
n2 = Pm.CDbl("3,14") 'In n1 is stored the same value as in n2
