FINT
Operation:
S ROUND TO INTEGER
(parallel data bus move)
Description:
Round the floating-point source operand S to an integer value using the current rounding mode specified
by bits R1-R0 in the IER register, and store the result as a floating-point number in the specified destination
D. The rounding precision is always SEP. For example: if the rounding is to +
111.00; however if the rounding is to 0, - , or even, then 110.50 rounds to 110.0.
Input Operand(s) Precision: SEP Floating-Point.
Output Operand Precision: SEP Floating-Point.
