SpinAsm IDE issue with decimal numbers

[jrrossi]

Hey folks, this is my first post here and I'm a noob when it comes to FV-1 development.

I'm having a weird issue with SpinAsm IDE, which I couldn't find any info around.
Basically, whenever I use decimal numbers (eg: 0.123) the code simply does not work on the FV-1.
My current solution is to use rational numbers (eg: 2/3), which can be very inconvenient.
Has anyone ran into this issue as well? I'm on Windows 11 and tried older versions of SpinAsm and also running with Window 7 compatibility mode, but nothing seems to solve the issue.

Cheers!

Just as an example of what's happening, if I compile this code:

equ coeff 1.2
rdax adcl,coeff
wrax dacl,1.0
wrax dacr,0.0

This is what I get:


It's like anything after the decimal dot gets ignored.

For the sake of documentation, I reached out on the SpinSemi forum and got a solution: https://www.spinsemi.com/forum/viewtopic.php?t=984
It had to do with the region format set on my machine, after I set it to English (United State) the problem was fixed.

Was it expecting you to use a comma for a decimal point? I have never seen that in an IDE.

I tried using the comma, but it also broke the assembler syntax.

Let's just say that the Spin IDE was last updated several major versions of Windows ago. I did chat once with the guy who wrote it.

This is quite classic localization bug, don't know why it didn't think about this.

C++ printf with %f but localized for the user's country

I'm using the following C++ syntax to output a floating point value on a Windows platform: printf("%.2f", 1.5); It works well if I run it on an English user account. My assumption was that if I r...

How to parse numbers like "3.14" with scanf when locale expects "3,14"

Let's say I have to read a file, containing a bunch of floating-point numbers. The numbers can be like 1e+10, 5, -0.15 etc., i.e., any generic floating-point number, using decimal points (this is f...

They are probably using localized string parsing functions, so I don't think it has to do with how old the software is.
