IEEE 754 Single Precision Floating Point System:

Determine the smallest floating point number x greater than 1 that can be

represented exactly in a binary single precision floating point system.

Determine the quantity ε = x - 1 (This is called machine epsilon).

32 bits.

1 bit sign

8 bits for exponent

23 bits for significand

I'm thinking something like -

0|01111111|00000000000000000000001

Which equals 1.0000001
