Converting REAL,32 Example:

The instrument returns the following values in REAL,32 format:

1. Convert from little endian to big endian:

2. The binary representation of the real portion, C3 14 06 25 is:

11000011000101000000011000100101

3. Binary is in IEEE format:

• 1st bit is sign bit

• next 8 bits are exponent

• next 23 bits are normalized value

4. Convert binary to decimal:

1, the MSb is the sign bit

10000110, exponent. The actual exponent value is this value minus 127. So, it is

134 – 127 = 7.

00101000000011000100101 (as normalized value) and adding 1 and multiplying

by 2^exponent results in 1+(0/2+0/4+1/8+0/16+1/32+0/64+...) * 2^7 = -148.024

(taking into account the sign bit) (approx.)
