Function

FVAL(449) converts the specified ASCII text number (starting at word S) to a 32-bit floating-point num-

ber (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:

Up to 6 characters are valid, excluding the sign, decimal point, and exponent. Any characters beyond

the 6th character will be ignored.

•Decimal Notation

Real numbers expressed with an integer and fractional part.

Example: 124.56
