or >=F (334)
Compares the specified single-precision data (32 bits) or constants
and creates an ON execution condition if the comparison result is true.
Three kinds of symbols can be used with the floating-point symbol
comparison instructions: LD (Load), AND, and OR.
LD:
Not required
AND or OR:
Required

CJ1-H, CJ1M, or
CS1D only)
FSTR
@FSTR
448
Converts the specified single-precision floating-point data (32-bit deci-
mal-point or exponential format) to text string data (ASCII) and outputs
the result to the destination word.
Output
required
505
ASCII TO FLOAT-
ING-POINT (CJ2,
CS1-H, CJ1-H,
CJ1M, or CS1D
only)
FVAL
@FVAL
449
Converts the specified text string (ASCII) representation of single-pre-
cision floating-point data (decimal-point or exponential format) to 32-bit
single-precision floating-point data and outputs the result to the desti-
nation words.
Output
required
