(import "libc.so.6" "strtof" "float" "char*")
(println (strtof "3.07"))
result = 3

With comma:
(import "libc.so.6" "strtof" "float" "char*")
(println (strtof "3,07"))
result = 3,069999933242798

There is a library, called exodriver downloadable from 'labjack' which gives its library version (2.07) as a 32 bit float through it's function LJUSB_GetLibraryVersion().This I have verified by importing this function in another programming language.

But newLisp v10.76 returns a value 0 instead of 2.07 when the following expression is used:

(import "liblabjackusb.so" "LJUSB_GetLibraryVersion" "float") followed by (LJUSB_GetLibrarVersion) returns a value 0 instead of 2.07.

Perhaps that is because "float" is a cut down version of "double"?

I just checked that there is segmentation fault reading a flost from libc on linux 64 bit, as follows:

(import "libc.so.6" "strtof" "float" "char*")
(strtof "2.07")
yields segmentation fault.

I would appreciate if this issue is resolved.

Yes! That works well now. Thank you. What was wrong with the code?

oh!

This code works.

@vashushpanov Thank you for the script! 🙏

I just tried to run your script on a file that I wanted to clean up. Sadly there was zero output.
I'm running newLISP v.10.7.5 64-bit on Linux IPv4/6 UTF-8, so maybe the regex you use in the script need to be updated? I get no error messages - just zero output!

It is a long time ago I was get this script.

Thx ...

I normally use Parinfer

Is there one hiding somewhere? I searched this Forum and the Home site w/o any luck.

From the newLISP manual:

QuotenewLISP has two types of basic arithmetic operators: integer (+ - * /) and floating point (add sub mul div).
The arithmetic functions convert their arguments into types compatible with the function's own type: integer function arguments into integers, floating point function arguments into floating points.
