Many Microsoft run-time library functions require floating-point support from a math coprocessor or from the floating-point libraries that accompany the compiler. Floating-point support functions are loaded only if required. When you use a floating-point type specifier in the format string of a cal...
There is no run-time error checking to detect if a format specifier isused for which support is not included. The --printf_support optionprecedes the --run_linker option, and must be used when performingthe final link. Joseph Raslavsky 11 年多前 in reply to Dr.No Expert 1620 points ...
The "%.0f" format specifier tells sprintf to format the float value as an integer. sprintf(myCharArray, "%.0f%.0f", myFloatArray[0], myFloatArray[1]); Also notice the answer provided in this post where snprintf is suggested for safety reasons. snprintf(myCharArray, sizeof(myCharA...
So basically the %a format specifier outputs the full precision, which is why you're getting b'3.1400000000000001' instead of b'3.14' and you're calling testformat(b"%a", (3.14,), b"3.14"), which formats the floating-point number 3.14 using %a in bytes format. So I THINK the assert...
(e.g.,"1.23E-7"). Verify whether the desired format is strictly decimal or scientific notation. If scientific notation is desired for large or small floats, replace"{x:.9f}"with a more suitable specifier like"{x:.9g}"or a custom formatting function that selectively uses scientific ...

The format specifiers supported by the NSString formatting methods and CFString formatting functions follow the IEEE printf specification; the specifiers are summarized in Table 1. Note that you can also use the “n$” positional specifiers such as %1$@ %2$s. For more details, see the IEEE ...
