## Base X To Number FunctionMath Miscellaneous Class

```Public Function BaseXToNumber( _
ByVal vString As Variant _
, Optional ByVal vBase As Variant _
) As Variant```

### Convert a number whose base is assumed to be vBase into a base-10 Double (precision floating-point) value.

Examples:
```    BaseXToNumber("10101011101", 2) = 1373
BaseXToNumber("23", 8) = 19
BaseXToNumber("377", 8) = 255
BaseXToNumber("12345", 8) = 5349
BaseXToNumber("-3456", 8) = -1838 ' #5
BaseXToNumber("23", 16) = 35
BaseXToNumber("FFFF", 16) = 65535
BaseXToNumber("12345678", 16) = 305419896
BaseXToNumber("AZ", 36) = 395
BaseXToNumber("ABC", 36) = 13368
BaseXToNumber("12345678", 36) = 82906087076
BaseXToNumber("AZABCDE", 36) = 23901464930
BaseXToNumber("ABCDEFGHI", 36) = 29100036563766
BaseXToNumber("ABCDEFGHIJKL", 36) = 1.35769130591909E+18```
```    NumberToBaseX Function
BaseXToLong Function```
Summary: This function can convert any numeric string whose base is between 2 and 36. Use base 2 for binary numbers, base 8 for octal numbers, base 10 for decimal numbers, base 16 for hexadecimal numbers, and base 36 for alphanumeric numbers. This function accepts negative numbers as indicated by a leading minus sign ("-") as in example #5.

vString: String containing the number in base vBase which will be converted to base 10 and returned as a Double value. Function returns Null if vString is Null or cannot be fixed up to a String.

vBase: The number base from which vString will be converted to base 10. vBase defaults to 10 (ten) if it is missing or Null or cannot be fixed up to a number. Function sets the base to 2 if vBase is less than 2.

Note: Function ignores characters in vString which are outside the range of those required to represent numbers of the specified base. For example, if the base if 2, this function will ignore all characters but "0" and "1" (and possibly a leading "-" which would indicate a negative number).
