How can I calculate the value of pi in PHP up to X decimal numbers. 4 decimal points 3.141 64 decimal points 3.141592653589793238462643383279502884197169399375105820974944592 Found the source for the broken link @Konamiman posted. Compared the results to: http://www.angio.net/pi/digits/50.txt and they are the same. // Source: http://mgccl.com/2007/01/22/php-calculate-pi-revisited function bcfact($n) { return ($n == 0 || $n== 1) ? 1 : bcmul($n,bcfact($n-1)); } function bcpi($precision) { $num = 0;$k = 0; bcscale($precision+3); $limit = ($precision+3)/14; while($k < $limit) { $num = bcadd($num,

how do you overwrite the previous print in python 2.7? I am making a simple program to calculate pi. here is the code: o = 0 hpi = 1.0 i = 1 print "pi calculator" acc= int(raw_input("enter accuracy:")) if(acc>999999): print "WARNING: this might take a VERY long time. to terminate, press CTRL+Z" print "precision: " + str(acc) while i < acc: if(o==0): hpi *= (1.0+i)/i o = 1 elif(o==1): hpi *= i/(1.0+i) o = 0 else: print "loop error." i += 1 if i % 100000 == 0: print str(hpi*2)) print str(hpi*2)) It basicly outputs the current pi after 100000 calculations. how can I make it overwrite the previous

I am fairly new to programming, but it seems like the π(pi) symbol is not in the standard set of outputs that ASCII handles. I am wondering if there is a way to get the console to output the π symbol, so as to express exact answers regarding certain mathematical formulas. I'm not really sure about any other methods (such as those that use the STL) but you can do this with Win32 using WriteConsoleW : HANDLE hConsoleOutput = GetStdHandle(STD_OUTPUT_HANDLE); LPCWSTR lpPiString = L"\u03C0"; DWORD dwNumberOfCharsWritten; WriteConsoleW(hConsoleOutput, lpPiString, 1, &dwNumberOfCharsWritten, NULL);

This C program is just 143 characters long! But it “decompresses” into the first 10,000 digits of Pi . // Created by cheeseMan on 30/11/13. long a[35014],b,c=35014,d,e,f=1e4,g,h; int main(int argc, const char * argv[]) { for(;(b=c-=14); h=printf("%04ld",e+d/f)) for(e=d%=f;(g=--b*2);d/=g) d=d*b+f*(h?a[b]:f/5), a[b]=d%--g; } I was doing some research on loss-less compression algorithms, still no luck yet, when I came across this pitiny.c . The weird thing is that it compiles successfully no errors or bugs, but like i said i cannot make heads or tales of the code, even its syntax. I just would

I have U and V wind component data and I would like to calculate wind direction from these values in R. I would like to end up with wind direction data on a scale of 0-360 degrees, with 0° or 360° indicating a wind blowing to the north, 90° indicating a wind blowing to the east, 180° indicating a wind blowing to the south and 270° indicating a wind blowing to the west. Below is some example data: > dput(wind) structure(list(u_ms = c(-3.711, -2.2417, -1.8188, -1.6164, -1.3941, -1.0682, -0.57611, -1.5698, -1.4976, -1.3537, -1.0901, -0.60403, -0.70812, -0.49045, -0.39849, 0.17875, 0.48356, 1.5082
