Floating-point constants with the DCFS directive don't seem to work in Keil uVision V5.38.

The following errors with 'unexpected token in argument list' with the carat under the first character of the value.

.ltorg

plusone DCFS 1.0
plusone DCFS 0x7f800000

Why is this failing?

Probably because that's legacy ARM assembly syntax, but your current version of MDK is not using a legacy ARM assembler any more.
