Your question is not clear. "General" is a display format, while IEEE 754 is
a method of storing a number. Please clarify what you want.

gives details on IEEE 754 double precision storage. Single precision is
similar, but with 8 bits (11 for DP) for the exponent and 23 bits (52 for DP)
for the mantissa.
