APPENDIX C
Consequently hi word= 4124 and lo word = CCCD
2. - 0.0000045
sign bit = 1
Exponent = -18, therefore exponent field = 127 + (-18) = 109 , and bits 30 to 23 = 0110 1101
The mantissa = 1.179648 which in binary representation = 1001 0110 1111 1110 1011 0101
i.e. (1x2-18) + (1x2-21) + (1x2-23) etc. = 0.0000045
Therefore the word value = 1011 0110 1001 0110 1111 1110 1011 0101
= B696FEB5
