This function converts a signed long integer to a null-terminated ASCII string. It accepts a pointer to a string buffer, a value to be converted to a string representation, and the radix in which to represent the number.
Radix may be one of the following:
Table 1. Radix options
radix | representation |
|---|---|
2 | Binary |
8 | Octal |
10 | Decimal |
16 | Hexidecimal |
The string buffer must be long enough to contain all characters created by the conversion. Therefore, the buffer must be sized as follows:
Table 2. Required buffer sizes
representation | size |
|---|---|
Binary | 18 bytes |
Octal | 8 bytes |
Decimal | 7 bytes |
Hexadecimal | 6 bytes |
