FLOOR
Operation:
S ROUND TO INTEGER
(parallel data bus move)
Description:
Round the floating-point source operand S to an integer value using the round to minus infinity mode and
store the result as a floating-point number in the specified destination D. The rounding precision is always
SEP. FLOOR is equivalent to FINT with R1, R0 in the IER set to select minus infinity; however, the round-
ing mode does not need to be saved, changed, and recalled. This is particularly useful when using C since
FLOOR is a standard C function.
Input Operand(s) Precision: SEP Floating-Point.
Output Operand Precision: SEP Floating-Point.
