Emily Berk commented on FELIX-5306:
-----------------------------------

I encountered this issue as well for {{org.apache.felix.fileinstall}} 3.6.0.

For {{myfloatProperty=F"10.5"}}, I get
{code}

{code}


I didn't have luck trying other variations:
{{myfloatProperty==f"10.5"}}
{{myfloatProperty=F10.5}}
{{myfloatProperty=f10.5}}
{{myfloatProperty=F"0x41280000"}} (IEEE 757 format)
{{myfloatProperty=f"0x41280000"}}
{{myfloatProperty=F0x41280000}}
{{myfloatProperty=f0x41280000}}

Documentation should be updated to explain the syntax for floats and doubles.

> The format for specifying a float in the .config format is <key>=F"<float value> and similarly for doubles but with the type character D.
> When the floats and doubles are encountered in the config, java.lang.NumberFormatException is thrown with the message like:
> {code}
> java.lang.NumberFormatException: For input string: "400.333"
> 	at java.lang.NumberFormatException.forInputString(NumberFormatException.java:65)
> 	at java.lang.Integer.parseInt(Integer.java:580)
> 	at java.lang.Integer.parseInt(Integer.java:615)
> {code} 
> The code is actually parsing using Integer and Long classes!!
