Any tips to correct this?Example;Enter a float number: -34.5Binary: 1101 1110.1 #-33.5The output is incorrect,Because:1 1 0 1 1 1 1 0 1-128+64+0+16+8+4+2+0+0.5= -33.5
The output should be:1101 1101.1 #-34.5
Because:1 1 0 1 1 1 0 1.1-128+64+0+16+8+4+0+1+.5 = -34.5

My code doesn't have incorrect problem, if the expected output is integer(negative or positive) and float(positive only).The problem only arise if the expected output is float and also negative.
What i want is, if the input is negative float. The output should be correct.
