Issue description

The remap math function returns nan and inf in valid cases making the function useless.

Steps to reproduce

Look at this code after you download the project and run it...

	var animation_speed := remap(player.velocity.x, 0.0, signf(player.direction) * walk_velocity_max, 0.0, 1.0)
	if  animation_speed == NAN: animation_speed = 0.0
	print(animation_speed)

Thanks for the report, Can you let me know if this still happens in the 26.1 beta? https://github.com/Redot-Engine/redot-engine/releases/tag/redot-26.1-beta.0

I found the cause, it's because the function divides so if the right hand of the division is zero it fails.

I can test later.
