Function
FIX
FIX(450) converts the integer portion of the 32-bit floating-point number in S+1 and S (IEEE754-format)
to 16-bit signed binary data and places the result in R.
Only the integer portion of the floating-point data is converted, and the fraction portion is truncated.
Example conversions:
A floating-point value of 3.5 is converted to 3.
A floating-point value of –3.5 is converted to –3.
FIXL
FIXL(451) converts the integer portion of the 32-bit floating-point number in S+1 and S (IEEE754-for-
mat) to 32-bit signed binary data and places the result in R+1 and R.
Only the integer portion of the floating-point data is converted, and the fraction portion is truncated.
Example conversions:
A floating-point value of 2,147,483,640.5 is converted to 2,147,483,640.
A floating-point value of –214,748,340.5 is converted to –214,748,340.
