7.3.8.10 DIV (divider)

Brief description

REAL-type divider with two inputs

Mode of operation

This function block divides the value entered at input X

by the value entered at input X

. The

result is output at the outputs as follows:

● Y output: Quotient with places before and after the decimal point

● YIN output: Integer quotient

● MOD output: Division remainder (absolute remainder value, MOD = (Y - YIN) × X0)

The Y output is limited to a range of approx. -3.4E38 to +3.4E38.

If output value Y exceeds the permissible value range of approx. -3.4E38 to 3.4E38

(because divisor X

is very small or zero), the limit value of the output range with the correct

sign is output at the Y output. At the same time, digital output QF is set to 1.

With a division of 0/0, block output Y remains unchanged. Digital output QF is set to 1.

7.3.8.11 AVA (absolute value generator with sign evaluation)

Brief description

REAL-type arithmetic function block for generating absolute values

Mode of operation

This function block generates the absolute value of the value present at input X. The result is

output at output Y.

Y = |X|

If the input variable is negative, digital output SN is set to 1.
