How can I mult开发者_StackOverflow中文版iply and divide using only bit shifting and adding? To multiply in terms of adding and shifting you want to decompose one of the numbers by powers of two, like
I am currently designing and implementing a small programming language as an extra-credit project in a class I\'m taking. My problem is that the language has three numeric types开发者_StackOverflow: L
I am working on the firmware for a device that uses an 8bit mcu (8051 architecture). I am using SDCC (Small Device C Compiler). I have a function that I use to set the speed of a stepper motor that my
System.out.println((26.55f/3f)); or System.out.println((float)( (float)26.55 / (float)3.0 )); etc. returns the result 8.849999.not 8.85 as it should.
Let\'s say I have these two floats: a = 50.0 b = 1048576.0 c = a/b By printing c, I get this: 4.76837158203125e-005
开发者_如何转开发I don\'t really understand how modulus division works. I was calculating 27 % 16 and wound up with 11 and I don\'t understand why.
does the following integer arithmetic property hold? (m/n)/l == m/(n*l) At first I thought I knew answer (does not hold), but now am not sure.
I am working on GPU device which has very high division integer latency, severa开发者_运维技巧l hundred cycles.I am looking to optimize divisions.
I was trying to divide (float)200 / (float)500 but the result is 0.0. Why is this so and how ca开发者_如何学Gon we have 0.4 as the result? Thanks a lot.It is a very common mistake, every programmer ma
