Formatting floats and ints

[Darts via Digitalmars-d-learn]

Thanks! That works perfectly! ;) I'll remember they're called 
Format Strings now.

Tangentially related follow up: if I want to cast a string to a 
dstring... what are the rules for that? I'm getting an 
"object.Error@(0): array cast misalignment" message when my 
program crashes tring to convert a string to a dstring...
