Subject: How to output "0" after paste() ?

Hi everyone,



How to get "0" after init?



aa&lt;- seq(2,7,0.5)



aa 



[1] 2.0 2.5 3.0 3.5 4.0 4.5 5.0 5.5 6.0 6.5 7.0



bb&lt;- paste("why no dot zero",aa,"after init",sep="")



bb



the output are:



[1] "why no dot zero2after init"   "why no dot zero2.5after init" 

[3] "why no dot zero3after init"   "why no dot zero3.5after init" 

[5] "why no dot zero4after init"   "why no dot zero4.5after init" 

[7] "why no dot zero5after init"   "why no dot zero5.5after init"

 [9] "why no dot zero6after init"   "why no dot zero6.5after init"

[11] "why no dot zero7after init" 



What I want are like: "why no dot zero2.0after init"  ,"why no dot zero3.0after init"



I used round(), signif(), but it does not help. Any ideas?
