- What is the sign bit of 1.0? 0 (for positive)
- What is the mantissa of 1.0? 000 0000 0000 0000 0000 0000
- What is the actual exponent of 1.0? 0
- What is the biased exponent of 1.0? 127
_{10}= 0111 1111_{2}

Fitting each of these pieces into their proper fields gives us the full 32 bits:

If the bit pattern is written in hexadecimal it is `0x3F800000`

.
To check that this is correct,
use SPIM.
Write a program that declares a floating point 1.0,
then run SPIM.

## Program to represent 1.0 .text .globl main main: .data val: .float 1.0 ## End of file

When you load this program in SPIM, where will the 1.0 be?
