System information

macOS 14.5.0, M2 Pro, Vulkan

Issue description

Re-saving a text scene/resource as another text scene/resource with float properties results in a loss of precision when the float has a precision of >6.

This is an issue with String::num_scientific;

The default for printf('%lg') is 6 precision.

Steps to reproduce

Open the MRP an editor
Re-save main.tscn as main-2.tscn
Observe that MobTimer.wait_time has reduced in precision from 0.570710678118 to 0.570711

This might be a duplicate of #78204 In either case, #98750 should fix this issue. Do you mind testing out #98750 and confirming?

[nikitalita]

yup, that fixes it.
