Fixed point on microprocessors is typically preferred in place of floating point. The Naive programmers can unknowingly encumber their firmware with printf, strtod, and associated if they do not know this. reprint supports fixed point output.

/* Printing to the hundredths place -> "42.042" */
int x = 42042;
reprint("\f3<r", x); 

/* Printing to the hundredths place with printf*/
printf("%u.%03u", x/ 1000, x%1000);

In reprint, we simply load 2 into Register 3 (identified by the "<" character). This is the amount we shift the decimal point to the left. When printing this requires no extra calculation. Oh, and if the 2 is omitted, the shift factor is specified as part of the varargs.

In printf, we much calculate 2 separate values, a division by a 100 and a remainder, in order to split up our source value into the integral and fractional part. We must also remember to zero pad the second number so the leading zeros show up.

Which one do you think is simpler?
