strtofloatdef?

[Robz]

How do I use strtofloatdef?
Something changed, the function previously was simple.
strtofloatdef(s: string, default: extended; format: string): extended;
where format, example: '##.00'
I get an error if I use this string format; expecting TFormatSettings.
What is TFormatSettings and how do I get the format equivalent of '#.00'?
Why the added complexity, it was previously simple to use.
Has quantum physics changed history?

It seems you're using ancient version of the compiler. What is the version of your Lazarus/FPC?

Information of StrToFloat and TFormatSetting can be found here:

Example how to use TFormatSetting:

Actually both version of StrToFloadDef exists in a superposition(see attachment). When you made a measurement you collapsed the wave function.

Handoko, thank you for your reply. I am using Version 1.6.2 with FPC 3.0.0. However, I believe my question must be better defined. Thinking about the requirement, formatting should be applied to a string. I will probably get a pointless result converting a formatted text number to a double floating point number.
Thanks again, Robert
