Converting numbers



Converting numbers

* Hexadecimal to Decimal:
Sub Form_Load ()

	Dim x as String
	Dim y as Variant

	x = "fffe"
	y = CLng("&H" & x)

	If y < 0 Then y = y + 65536    ' returns 65534
	
	MsgBox y

End Sub


* Converting a string to an integer: Cal Stover

Dim SomeVariable as Integer
SomeVariable = CInt(Label2.Caption) + 100

Dim SomeVariable as Single
SomeVariable = CSng(Val(Label2.Caption) + 100)


* convert a number in Hexadecimal to Binary -chris

A very fast conversion from hex to binary can be done with a sixteen
element look-up table - a single hex digit converts to four binary
digits.  So:

Function Hex2Bin$(HexValue$)
  CONST BinTbl ="0000000100100011010001010110011110001001101010111100110111101111"
  dim X, Work$
  Work$ = ""
  For X = 1 to Len(HexValue$)
    Work$ = Work$ + Mid$(BinTbl, (Val("&h" + Mid$(HexValue$, X, 1) - 1) * 4 + 1, 4)
  Next
  Hex2Bin$ = Work$
End Function

You could also code BinTbl as an array which would eliminate one of the
Mid$() calls, but then the array would either have to be built ahead of
time or built every time you called the Hex2Bin function.  You could try
all three options and see which is faster.

Program Print Fibonacci Series in a Range
Fibonacci series is a series of numbers where the current number is the sum of previous 2 terms. For Example: 0, 1, 1, 2, 3, 5, 8, 13, 21,... Here c is the current term, b is the n-1th term

Checking Singly Linked List is Palindrome
C Program checks whether the Singly Linked list is a palindrome. A Palindrome is a Pattern in List in which the contents when read from front is the same as when read from last. So
