• 32 bits
• The first bit is the sign bit, 0 for positive
• The next 8 bits represent the exponent, in 127-bias notation
• This leaves 23 bits for the mantissa

This format will be able to represent numbers in the range $\approx {10}^{-38}\to {10}^{38}$
With approximately 7 decimal digits of precision
