In the preamble:

\newenvironment{wrappednumbers}
{\count0=`\9 \loop \ifnum\count0>`\0
  \uccode`\~=\count0\uccode`\!=\count0
  \lowercase{\def~{!\penalty0}}
  \catcode\count0=\active
  \repeat
  \uccode`\~=0 \uccode`\!=0}{}

and then 

\begin{wrappednumbers}
3.141592653589793238462643383279502884197169399375105820974944592307816%
