Floating point number - verify please

if the floatingpoint number is 1111111111111111111111111111111,
the answer should be NaN instead of infinity rite?

 

sorry. it should be right, not rite. pardon me.

from your statement, i conclude that the exact answer should be infinity.
am i right?

what if, i have this floating point number : 11111111100000000000000000000000
and i am to convert this floating point number to decimal, the answer should be infinity, isn't it?

then can i summarise that if the exponential is all 1's, it will be infinity when converted to decimal?

thank you.

 

tq. btw, i just found this in the internet.

# Infinity is encoded when the exponent field is all 1’s and the mantissa is all 0’s.
# If the exponent contains all 1’s but the mantissa does not contain all 0’s, then this is referred to as NaN or Not a Number.
