3.22.3 Real multiplication MULR
3.22.3.1 Function block
Figure 174: Function block
3.22.3.2 Functionality
The real multiplication function MULR multiplies the real input REAL_IN1 by the real
input REAL_IN2 together. MULR executes the equation
REAL_OUT = REAL_IN1 x REAL_IN2
If the value of the product is outside the range, then the output quality is set as
bad and VALID is set to FALSE. The minimum negative product value is restricted to
-2097152.000 and the maximum positive product value is restricted to 2097152.000.
