CVD
Converts an eight byte string to a double-precision variable
Syntax
`
Declare Function CVD ( ByRef str As Const String ) As Double
`
Usage
`
result = CVD( str )
`
Parameters
`str`
A String exactly eight bytes in length with a binary copy of a double-precision variable stored in it.
Return Value
Returns a Double-Precision variable to copy the binary copy of a double to.
Description
Does a binary copy from a 8-byte-string to a double-precision variable. The result will have a sense only if the string contained a IEEE754 formated double value, as the one generated by `MKD`.
This function is useful to read numeric values from buffers without using a `Type` definition.
Example
`
Dim a As Double, b As String
a=4534.4243
b=MKD(a)
Print a, CVD(b)
Sleep
`
