--- Compares the specified single-precision data ( 3 2 bits) or con-
stants and creates an ON execution condition if the comparison
result is true.
FLOATING-
POINT TO
ASCII FSTR @ Converts the specified single-precision floating-point data ( 3 2-bit
decimal-point or exponential format) to text string data (ASCII) and
outputs the result to the destination word.
C: First Control Word
Note There are limits on the total number of characters and the
number of fractional digits.
ASCII TO
FLOATING-
POINT FVAL @ Converts the specified text string (ASCII) representation of sin-
gle-precision floating-point data (decimal-point or exponential for-
mat) to
3 2-bit single-precision floating-point data and outputs the
result to the destination words.
