CVL
Converts a single-precision floating-point number or four-byte string to an integer (long) variable
Syntax:
declare function Cvl ( byval sng as single ) as long
declare function Cvl ( byref str as const string ) as long
declare function Cvl ( byref str as const string ) as long
Usage:
result = Cvl( sng )
result = Cvl( str )
result = Cvl( str )
Parameters:
sng
A Single floating-point number with a binary copy of an integer variable stored in it.
str
A String at least four bytes in length with a binary copy of an integer variable stored in it.
Return Value:
A long variable to copy the binary copy of a integer to.
Description:
Returns a 32-bit Long integer value using the binary data contained in a Single, or a String of at least four bytes in length. A value of zero (0) is returned if the string is less than four bytes in length.
Cvl is used to convert 4-byte strings created with Mkl.
This function can also be used to convert 32-bit integer values from a memory or file buffer without the need for a Type structure. However, just as with the type structure, special care should be taken when using Cvl to convert strings that have been read from a buffer.

Examples:
Dim l As Long, s As String
s = "ABCD"
l = CVL(s)
Print Using "s = ""&"""; s
Print Using "l = &"; l
s = "ABCD"
l = CVL(s)
Print Using "s = ""&"""; s
Print Using "l = &"; l
Differences from QB:
- In QB an error occurs if the string passed is less than four bytes in length.
- QB did not support floating-point arguments.
