C to c++ converter

[mpgasiva]

/*
** File: U2LNumberFormat.c
** Author: David McAteer
** Date: 12-29-98
**
** Purpose: Is to format numbers to the desired format in crystal reports.
** Example: FormatNumber(23.300700, 0) = 23.3007
** FormatNumber(23.32, 0) = 23.32
** FormatNumber(23.324, 1) = 23.32
** FormatNumber(10.00, 0) = 10
** Arguments: NumberFormat(Number to format, Desired format)
** Desired format: 0 - Normal Format, 1 - Currency Format

Why? Most C code will compile as C++; have you even tried? If so, what were the issues or errors?
