Numeric comparison: 9 < 10 but 16.9 > 16.10

### Issue Description

MSBuild seems to recognize integers when using inequality operators with string operands (which is good), but it fails to recognize floating point numbers as numeric, instead treating them like ordinary strings. This leads to unexpected evaluation of the conditionals.

As shown in the repro steps, MSBuild recognizes that `9 < 10`, but fails to recognize that `16.9 < 16.10`. It *does* recognize 4-component versions though, recognizing that `16.9.0.0 < 16.10.0.0`.

### Steps to Reproduce

```xml

```

### Expected Behavior

```
'9' <= '10'
true
'16.9' <= '16.10'
true
'16.9.0.0' <= '16.10.0.0'
true
```

### Actual Behavior

```
'9' <= '10'
true
'16.9' <= '16.10'
'16.9.0.0' <= '16.10.0.0'
true
```
