Hi,

Is there a simple way to format a Float into an X decimal place Str? I'm thinking of something similar to Java's:

String.format("%.2f", floatValue)

Cheers.

You probably want to look at:

• http://fantom.org/doc/sys/Float.html#toLocale
• http://fantom.org/doc/sys/Float.html#toStr

For the latter you'll also have to look at the following:

• http://fantom.org/doc/sys/Str.html#justl
• http://fantom.org/doc/sys/Str.html#justr
• http://fantom.org/doc/sys/Str.html#padl
• http://fantom.org/doc/sys/Str.html#padr

Between these you can emulate most of String.format.

λ ~ → fansh
Fantom Shell v1.0.62 ('?' for help)
fansh> 12345.6789f.toLocale("0.00")
12345.68
fansh> 12345.6789f.toLocale("0.00").padl(10,'0')
0012345.68

Awesome! I skipped over sys::Float#toLocale thinking it was just boring I18N stuff!
