ios - Converting number to format with NSNumberFormatter -

-

how can convert number 4273095782 number 4 273 095 782 nsnumberformatter?

i use diode not it

nsnumberformatter *formatter = [[nsnumberformatter alloc] init]; formatter.numberstyle = kcfnumberformatterdecimalstyle; formatter.maximumintegerdigits = 3; formatter.minimumfractiondigits = 3; formatter.groupingseparator = @" "; formatter.decimalseparator = @" "; nsstring *formattednumber = [formatter stringfromnumber:p];

you need use 2 properties : setgroupingsize: last 3 digits , setsecondarygroupingsize: other digits:

the complete implementation go this: 

nsinteger integer = 4273095782; nsnumberformatter * formatter = [nsnumberformatter new]; [formatter setnumberstyle:nsnumberformatterdecimalstyle]; [formatter setgroupingsize:3]; [formatter setsecondarygroupingsize:3]; [formatter setgroupingseparator:@" "]; nsstring * threeseparated =  [formatter stringfromnumber:@(integer)]; nslog(@"threeseparated: %@", threeseparated);

output: 4 273 095 782

i'm trying plot frequency characteristic equation using ezplot, matlab gives following warning, "contour not rendered non-finite zdata". have used command plot frequency equations warning , plot display empty , not change axis range well. can please help. appreciated. here's code i'm using. % transfer matrix case-i, thin rotor clear all; clc; ei = 1626; l = 0.15; m = 0.44108; = 2.178*10^-4; i_p = 2.205*10^-5; itr = 0.24; i_pr = 0.479; syms p n; f = [1 l*1i l^2/(2*ei)*1i l^3/(6*ei); 0 1 l/ei -l^2/(2*ei)*1i; 0 0 1 -l*1i; 0 0 0 l]; p = [ 1 0 0 0; 0 1 0 0; 0 -it*p^2+i_p*n*p 1 0; -m*p^2 0 0 1]; p_r = [1 0 0 0; 0 1 0 0; 0 -itr*p^2+i_pr*n*p 1 0; -m*p^2 0 0 1]; = f*p*f*p*f*p*f; b = p_r*f*p*f*p*f; r = a(1,2)/a(1,4); a12_p = 0; a22_p = a(2,2)-r*a(2,4); a32_p = a(3,2)-r*a(3,4); a42_p = a(4,2)-r*a(4,4); ap(2,2) = a22_p; ap(3,2) = a32_p; ap(4,2) = a42_p; ap(4,4) = 1; c = b*ap; m = [c(3,2) c(3,4); c(4,2) c(4,...

i using indy udp server read string of data. however, not know how work adata parameter. can around converting binary using bytetobin function below , convert hex using bintohex1 . feel stupid , works slow. know how can directly results without 2 conversions? thanks!! here codes: procedure tform1.idudpserver1udpread(athread: tidudplistenerthread; const adata: tidbytes; abinding: tidsockethandle); var buf: tidbytes; buffer: string; data_received: string; begin if bytestostring(adata) <> 'hello' begin buffer := hextostring('00'); setlength(buf, length(buffer)); copytidstring(buffer, buf, 0); abinding.sendto(abinding.peerip, abinding.peerport, buf); data_received := bintohex1(bytetobin(adata[1]) + bytetobin(adata[2]) + bytetobin(adata[3]) + bytetobin(adata[4]) + bytetobin(adata[5]) + bytetobin(adata[6]) + bytetobin(adata[7]) + bytetobin(adata[8]) + bytetobin(adata[9]) + bytetobin(adata[10]) + bytetobin(adata[11...
