1000 * 150 = 18928 ?!?

-

am insane?

code: [select]
serial.println(1000 * 150);
 serial.println(e12[i-1] * multiply_factor);

i'm trying work out why i'm getting unexpected values, second line should identical top line, , result same, life of me, cannot see heck going on...

help!

1000 integer. 150 integer. 150,000 not integer.

the compiler using integer arithmetic integer variables, expecting integer result, not get, given actual inputs.

the types of e12 , multiply_factor unknown, can not tell why works.

hello ! wrote today article on blog cpu load monitoring (using gpio , leds) on raspberry's. simple (written in little shell script), think can useful (for people want learn leds stuff on r. pi) there 5 leds turning on , off regarding cpu load: - cpu < 20%: 1 led - cpu < 40%: 2 leds - cpu < 60%: 3 leds - cpu < 80%: 4 leds - cpu < 90%: 5/5 leds - cpu >= 90%: 5 leds flashing here article: written in french, can watch youtube video , download code @ bottom of article. http://www.chteuchteu.com/2012/10/26/ra ... e-au-gpio/ if find errors in code, can post comment on article. ! up code enhancements ? raspberrypi
