FIXLD(842) converts the integer portion of the double-precision (64-bit) float-
ing-point number in words S to S+3 (IEEE754-format) to 32-bit signed binary
data and places the result in D+1 and D.
S+3CH S+2CH
D+1CH
Only the integer portion of the floating-point data is converted, and the fraction
portion is truncated. (The integer portion of the floating-point data must be
within the range of –2,147,483,648 to 2,147,483,647.)
Example conversions:
A floating-point value of 2,147,483,640.5 is converted to 2,147,483,640.
A floating-point value of –2,147,483,640.5 is converted to –2,147,483,640.

Operation
ON if the data in words S to S+3 is not a number (NaN).
ON if the integer portion of words S to S+3 is not within
the range of –2,147,483,648 to 2,147,483,647.
OFF in all other cases.
ON if the result is 0000 0000.
OFF in all other cases.
ON if bit 15 of D+1 is ON after execution.
OFF in all other cases.
