FLOAT

The FLOAT format consists of 4 bytes and is used when floating
decimal values are to be transmitted. The IEEE 754 format
should be used. The numerical range accepted by the recorder
lies within −9.990E9 and +9.990E9.

For example: transmit the value −12.5.

−12.5 dec = C1 48 00 00 hex

Determination of the hex figure

The general form of the floating decimal point is: (sign)

Exp−127

(Rest).

The binary display of the figure −12.5 is

11000001 01001000 00000000 00000000

Exp

Rest

(8 bit)

(23 bit)

negative sign

1. Calculate the sign:

the bit is set in case of a negative sign.

2. Calculate the exponent:

the highest exponent is calculated:

EXP = INT [lg”Figure

dec

”/lg2] + 127

in the example:
INT [lg12.5/lg2] + 127 = 130 dec = 82 hex = 10000010 bi-
nary

3. Calculate the rest:

Rest = “Figure

dec

”/2

Exp

in the example:
12.5/2

130 − 127

= 1.562

4. Transform into binary code:

Rank

: 2

+ 2

−1

+ 2

−2

+ 2

−3

+ 2

−4

+ ... +2

−23

In the example: 1

The value of 2

is always 1 and is therefore not carried for-

ward.
