At some point in an algorithm I need to compare the float value of a property of a class to a float. So I do this:
I was out looking for the rounding convention used by Perl\'s built-in function sprintf. I was thinking that it does a normal rounding (e.g. ROUND_HALF_UP as in Java\'s rounding mode convention), but
So, lets say I have 100,000 float arrays with 100 elements each.I need the highest X number of values, BUT only if they are greater than Y.Any element not matching this should be set to 0.What would b
Read this question carefully because I am not asking how to get rid of trailing zeros, that\'s easy. What I am asking is why does 123d become \"123.0\"?
Got a math calculation problem. $a = 34.56 $b = 34.55 $a do some calculation to get this figure $b is doing rounding to the nearest 0.05 to get this figure
Here\'s a small snippet of code, when called it outputs \'double\'. Why? What\'s the reasoning behind this. Why doesn\'t it print \'float\'?
I have a list of floats. If I simply print it, it shows up like this: [9.0, 0.052999999999999999, 0.032575399999999997, 0.010892799999999999, 0.055702500000000002, 0.079330300000000006]
what is the best w开发者_如何转开发ay to handle big integers in expr command. we know wide in expr.As of Tcl 8.5, integers are now Bignums (arbitrary precision)
Right now, the only function that I am aware of is _snprintf_s like the following double dMyV开发者_开发技巧alue = <some value>;
I just read a statement about the floating point value comparison Floating point values shall not be compared u开发者_JAVA技巧sing either the == or !=
