Format(PadCharacter, mBefore, nAfter, value)

Format, as its name implies, will format a number into a string containing at least nBefore characters on the left of the decimal point and exactly After characters after the decimal point.
You can specify a padding character to be used on the left of the decimal point, you will usually want a space or zero.
- If the pad string is empty then nFormat will be likely to fail in putting at least nBefore characters before the decimal dot.
- If the number is so great that it cannot fit in nBefore characters, it will NOT be truncated, and you will not get what you expected.
- If the pad string contains more than one character, only the first one will be used.

Return Value:
A formatted string containing a number.

Example:

print(Format("0", 4, 2, 0), "\n")
print(Format("0", 3, 1, 1.5), "\n")
print(Format("x", 3, 1, -1.5), "\n")
print(Format("0", 1, 1, -1.5), "\n")
print(Format(" ", 2, 1, 1.59), "\n")
print(Format(" ", 2, 1, -1.49), "\n")
print(Format(" ", 1, 3, 1.49), "\n")
print(Format("0", 3, 0, 1.5), "\n")
print(Format(" ", 2, 2, 1998), "\n")
