nPointer to integerNumber of characters (bytes) successfully written so far to thestreamor buffer; this value is stored in the integer whose address is given as the argument. pPointerPointer converted to a sequence of printable characters. It can be one of the following: ...
and is exhaustively tested on 32-bit and 64-bit architectures. nanoprintf does include C standard headers but only uses them for C99 types and argument lists; no calls are made into stdlib / libc, with the exception of any internal large integer arithmetic calls your compiler might emit. As...

bool, char, short, and unscoped enumerations are converted to int or wider integer types as in integer promotion So for example, float parameters are converted to doubles, and char’s are converted to int’s. If you actually needed to pass, for example, a char instead of an int, the...
Some implementations builds the full string before emitting, and some emits the data parameter for parameter and only need buffer space for the widest parameter (such as a zero-padded integer of large/extreme width). Does your code contain any sprintf()? They can result in really fu...
This optimization would be more efficient for very large numbers, while still using the current method for smaller numbers. 300-311: LGTM! Consider adding a comment for clarity. The changes to format_float function correctly handle the case when the number is an integer. This is a good optimi...
(optional) integer value or * that specifies minimum field width. The result is padded with space characters (by default), if required, on the left when right-justified, or on the right if left-justified. In the case when * is used, the width is specified by an additional argument of ...
converts a signed integer into decimal representation [-]dddd. Precision specifies the minimum number of digits to appear. The default precision is 1. If both the converted value and the precision are 0 the conversion results in no characters. signed char short int long long ...
