How do I finish converting from single precision floating point to decimal?
I am converting C22E8300 from a Single Precision IEEE 754 Floating Point to a decimal.
First, I converted to binary: 1100 0010 0010 1110 1000 0011 ...
Calculated the exponent as 5. The mantissa is 0.24762
How do I finish the conversion now?
