#84725 - Multiplication Problems and data types |
Hi, I am having problems with a calculation in the keil evaluation software. i cannot use floating point numbers since it is an evaluation version. My first problem is trying to convert the timers values into a 16-bit number and output to screen. I am trying to do the following:
totcount=(timehi * 256) + timelo; where i am assigning totcount as an unsigned int, timehi and timelo as an unsigned char and 256 as an int. if: timehi = 239 timelo = 0 when i output to screen, 'totcount' keeps giving me -4348 when the answer should be 61184 (decimal). Does anybody know what i am doing wrong! |

| Wrong printf format specifier? | 01/01/70 00:00 | |
| yes i am using printf | 01/01/70 00:00 | |
| manual! | 01/01/70 00:00 | |
