Well, first off, +it's *much* faster (see below). It's also much smaller than the CRT +versions code-space-wise. We've also added some simple improvements +that are super handy (commas in thousands, callbacks at buffer full, +for example). Finally, the format strings for MSVC and GCC differ +for 64-bit integers (among other small things), so this lets you use +the same format strings in cross platform code. + +It uses the standard single file trick of being both the header file +and the source itself. If you just include it normally, you just get +the header file function definitions. To get the code, you include +it from a C or C++ file and define STB_SPRINTF_IMPLEMENTATION first. + +It only uses va_args macros from the C runtime to do it's work. It +does cast doubles to S64s and shifts and divides U64s, which does +drag in CRT code on most platforms. + +It compiles to roughly 8K with float support, and 4K without. +As a comparison, when using MSVC static libs, calling sprintf drags +in 16K. + +API: +==== +int stbsp_sprintf( char * buf, char const * fmt, ... ) +int stbsp_snprintf( char * buf, int count, char const * fmt, ... ) + Convert an arg list into a buffer. stbsp_snprintf always returns + a zero-terminated string (unlike regular snprintf). + +int stbsp_vsprintf( char * buf, char const * fmt, va_list va ) +int stbsp_vsnprintf( char * buf, int count, char const * fmt, va_list va ) + Convert a va_list arg list into a buffer. stbsp_vsnprintf always returns + a zero-terminated string (unlike regular snprintf). + +int stbsp_vsprintfcb( STBSP_SPRINTFCB * callback, void * user, char * buf, char const * fmt, va_list va ) + typedef char * STBSP_SPRINTFCB( char const * buf, void * user, int len ); + Convert into a buffer, calling back every STB_SPRINTF_MIN chars. + Your callback can then copy the chars out, print them or whatever. + This function is actually the workhorse for everything else. + The buffer you pass in must hold at least STB_SPRINTF_MIN characters. + // you return the next buffer to use or 0 to stop converting + +void stbsp_set_separators( char comma, char period ) + Set the comma and period characters to use. + +FLOATS/DOUBLES: +=============== +This code uses a internal float->ascii conversion method that uses +doubles with error correction (double-doubles, for ~105 bits of +precision). This conversion is round-trip perfect - that is, an atof +of the values output here will give you the bit-exact double back. + +One difference is that our insignificant digits will be different than +with MSVC or GCC (but they don't match each other either). We also +don't attempt to find the minimum length matching float (pre-MSVC15 +doesn't either). + +If you don't need float or doubles at all, define STB_SPRINTF_NOFLOAT +and you'll save 4K of code space. + +64-BIT INTS: +============ +This library also supports 64-bit integers and you can use MSVC style or +GCC style indicators (%I64d or %lld). It supports the C99 specifiers +for size_t and ptr_diff_t (%jd %zd) as well. + +EXTRAS: +======= +Like some GCCs, for integers and floats, you can use a ' (single quote) +specifier and commas will be inserted on the thousands: "%'d" on 12345 +would print 12,345. + +For integers and floats, you can use a "$" specifier and the number +will be converted to float and then divided to get kilo, mega, giga or +tera and then printed, so "%$d" 1000 is "1.0 k", "%$.2d" 2536000 is +"2.53 M", etc. For byte values, use two $:s, like "%$$d" to turn +2536000 to "2.42 Mi". If you prefer JEDEC suffixes to SI ones, use three +$:s: "%$$$d" -> "2.42 M". To remove the space between the number and the +suffix, add "_" specifier: "%_$d" -> "2.53M". + +In addition to octal and hexadecimal conversions, you can print +integers in binary: "%b" for 256 would print 100. + +PERFORMANCE vs MSVC 2008 32-/64-bit (GCC is even slower than MSVC): +=================================================================== +"%d" across all 32-bit ints (4.8x/4.0x faster than 32-/64-bit MSVC) +"%24d" across all 32-bit ints (4.5x/4.2x faster) +"%x" across all 32-bit ints (4.5x/3.8x faster) +"%08x" across all 32-bit ints (4.3x/3.8x faster) +"%f" across e-10 to e+10 floats (7.3x/6.0x faster) +"%e" across e-10 to e+10 floats (8.1x/6.0x faster) +"%g" across e-10 to e+10 floats (10.0x/7.1x faster) +"%f" for values near e-300 (7.9x/6.5x faster) +"%f" for values near e+300 (10.0x/9.1x faster) +"%e" for values near e-300 (10.1x/7.0x faster) +"%e" for values near e+300 (9.2x/6.0x faster) +"%.320f" for values near e-300 (12.6x/11.2x faster) +"%a" for random values (8.6x/4.3x faster) +"%I64d" for 64-bits with 32-bit values (4.8x/3.4x faster) +"%I64d" for 64-bits > 32-bit values (4.9x/5.5x faster) +"%s%s%s" for 64 char strings (7.1x/7.3x faster) +"...512 char string..."
