FVAL(449) converts the specified ASCII text number (starting at word S) to a
32-bit floating-point number (IEEE754-format) and outputs the result to the
destination words starting at D.
FVAL(449) can convert ASCII text in decimal or scientific notation if it meets
the following conditions:
S: First source word
S
D: First destination word
