sql - How to change number of digits after decimal point? -

-

i have line in query:

case when count(n.counter) <> 0 (cast(count(n.counter) float)/count(t.counter)) * 100 else 0 end percent

i'm getting results 79.565974946. want result 80% (with no digits after decimal point , '%' sign). how can that?

you need round , then, because you're trying formatting, convert string before adding %:

convert(varchar(20), round( case when count(n.counter) <> 0       (cast(count(n.counter) float)/count(t.counter)) * 100      else 0 end ,0)) + '%' percent

also, there may typo here - looks you're trying avoid divide 0 error, you're testing wrong operand (n.counter rather t.counter) may still division 0 code.

i have data grid rows represent theta (0, pi) , columns represent phi (0, 2*pi) , f(theta,phi) density of dark matter @ location. wanted calculate power spectrum , have decided use healpy. what can not understand how format data healpy use. if provide code (in python obvious reasons) or point me tutorial, great! have tried hand @ doing following code: #grid dimensions nrows*ncols (subject change) theta = np.linspace(0, np.pi, num=grid.shape[0])[:, none] phi = np.linspace(0, 2*np.pi, num=grid.shape[1]) nside = 512 print "pixel area: %.2f square degrees" % hp.nside2pixarea(nside, degrees=true) pix = hp.ang2pix(nside, theta, phi) healpix_map = np.zeros(hp.nside2npix(nside), dtype=np.double) healpix_map[pix] = grid but, when try execute code power spectrum. specifically, : cl = hp.anafast(healpix_map[pix], lmax=1024) i error: typeerror: bad number of pixels if point me tutorial or edit code great. more specifications: data in 2d np array , can change numrows/...
