Nothing bad will happen, but the %d verb instructs the fmt package to print is as a number (using base 10), and the %v verb means to use the default format which can be overridden. See this example: type MyInt int func (mi MyInt) String() string { return fmt.Sprint(“*”, int(mi), “*”) } func main() { … Read more
There is now printf-like support in util.format(). Example: util.format(‘hello %s’, ‘world’); // Returns: ‘hello world’
The syntax is almost the same as printf. With printf you give the string format and its contents ie: printf(“my %s has %d chars\n”, “string format”, 30); With fprintf it is the same, except now you are also specifying the place to print to: FILE *myFile; … fprintf(myFile, “my %s has %d chars\n”, “string format”, … Read more
You want to use %g instead of %f: “%gx” % (factor / 100.00)
echo -n “Hello” | od -A n -t x1 Explanation: The echo program will provide the string to the next command. The -n flag tells echo to not generate a new line at the end of the “Hello”. The od program is the “octal dump” program. (We will be providing a flag to tell it … Read more
#include <inttypes.h> #include <stdint.h> printf(“%016” PRIxPTR “\n”, (uintptr_t)ptr); but it won’t print the pointer in the implementation defined way (says DEAD:BEEF for 8086 segmented mode).
No, that’s more or less what they’re meant to do. In C (and many other languages), you can insert hard-to-see/type characters using \ notation: \a is alert/bell \b is backspace/rubout \n is newline \r is carriage return (return to left margin) \t is tab You can also specify the octal value of any character using … Read more
“%030d” is the droid you are looking for
Instead of Googling for %02d you should have been searching for sprintf() function. %02d means “format the integer with 2 digits, left padding it with zeroes”, so: Format Data Result %02d 1 01 %02d 11 11
Since you’re looking for fourths (.00, .25, .50, .75), multiply your number by 4, round to nearest whole number as desired (floor if down, ceil if up), then divide by 4. 1.32, down to nearest fourth: 1.32 * 4 = 5.28 floor(5.28) = 5.00 5.00 / 4 = 1.25 Same principle applies for any other … Read more
