6.11 C++ How to Program (8th Edition) By Paul Deitel, Harvey Deitel

Show the value of x after each of the following statements is performed:

a)

 x = fabs( 7.5 )

b)

 x = floor( 7.5 )

c)

 x = fabs( 0.0 )

d)

 x = ceil( 0.0 )

e)

 x = fabs( -6.4 )

f)

 x = ceil( -6.4 )

g)

 x = ceil( -fabs( -8 + floor( -5.5 ) ) )

Solution:

Value of fabs( 7.5 ) is 7.5

Value of floor( 7.5 ) is 7

Value of fabs( 0.0 ) is 0

Value of ceil( 0.0 ) is 0

Value of fabs( -6.4 ) is 6.4

Value of ceil( -6.4 ) is -6

Value of ceil( -fabs( -8 + floor( -5.5 ) ) ) is -14
