Subject: What is 'single precision' for in fixed point 'Fixed-Point Basics'?

Hi,
The text below the dot line is except from Matlab help/Fixed-Point Toolbox. I do not understand the meaning of "single-precision". In the text I cannot relate single-precision to fixed-point in any means.

Could you explain it to me? Thanks

Many textbooks also do roundoff error analysis for "single-precision" fixed-point products and sums with fractional numbers. In this example, we simulate 8-bit unsigned fractional numbers (all values between 0 and 1).
U8 = numerictype('Signed',0,'WordLength',8,'FractionLength',8)
