xcode - How to round an NSDecimalNumber in swift? -

-

i can't find resources on this, , i've been trying sorts of stuff, nothing works.

according apple's documentation, round nsdecimalnumber this:

nsdecimalnumber.decimalnumberbyroundingaccordingtobehavior(<#behavior: nsdecimalnumberbehaviors?#>)

it takes in nsdecimalnumberbehavior, i'm unsure how manipulate since (1) cannot initiated variable , have it's properties changed, , (2) roundingmode() method according documentation doesn't take parameters, xcode fills in parameter space "self".

i'm totally lost on this. basic question; how can round nsdecimalnumber in swift?

thanks in advance

you can that

let x = 5 let y = 2 let total = x.decimalnumberbydividingby(y).decimalnumberbyroundingaccordingtobehavior( nsdecimalnumberhandler(roundingmode: nsroundingmode.roundup, scale: 0, raiseonexactness: false, raiseonoverflow: false, raiseonunderflow: false, raiseondividebyzero: false))

i have similar problem described in how prevent numbers being changed exponential form in python matplotlib figure : i don't want (in special case) weird scientific formatting of axis. problem different have problem @ z -axis. 2-d plots can use ax.get_yaxis().get_major_formatter().set_useoffset(false) . , there no function ax.get_zaxis() what use format z -axis same way? edit: example: from mpl_toolkits.mplot3d import axes3d import numpy np import sys import matplotlib import matplotlib.pyplot pyplot def func(xi, ti): res = 10e3 + np.cos(ti) * np.sin(xi) return res if __name__ == '__main__': timespacing = 20 timestart = 0 timeend = 1 time = np.linspace(timestart, timeend, timespacing) widthspacing = 50 widthstart = 0 widthend = 3 width = np.linspace(widthstart, widthend, widthspacing) reslist = [] matplotlib.rcparams['legend.fontsize'] = 10 fig = pyplot.figure() ax = fig.gca(projection = '3d...

i install web server database on raspberry pi (little computer). computer has 1gb ram. i want know best combination: linux distribution , web server , dbms run local server multiple users minimal latency, use php on server. , best settings performance , not have bugs (memory usage, disable plugin, disable service, etc)? i thought light debian , lighttpd server , sqlite database. solution? i think lighttpd + sqlite great choice. linux distro, debian @ centos or tiny core linux , although i'm not sure of compatibility pi. obviously, can't go wrong raspbian if want use in production , more stable performance, few more pi's , set them in cluster .
