Answer 1

Answers:

a. $-2$

b. $0.095$

c. $2$

d. $2$

e. $5$

f. $5$

g. $1$

Explanation:

a. Math.abs(-5)-Math.abs(-7)

• abs returns the absolute value of the given number or argument.
• The data type can be int, float, long, double.
• The value of Math.abs(-5) is 5.
• The value of Math.abs(-7) is 7.
• So, the value of Math.abs(-5)-Math.abs(-7) $= 5 - 7 = -2$.

b. Math.max($1.5$e-2,$0.095$)

• max returns the largest numbers of the two arguments .
• The data type can be int, float, long, double.
• The largest of $1.5$e-2 and $0.095$ is
• So, the value of Math.max($1.5$e-2,$0.095$) is $0.095$.

c. Math.round($1.49$+1)

• round returns the nearby int or long (as per the argument).
• Basically, it it used to round off the number.
• The datatype can be double or float.
• $1.49+1=2.49$.
• The nearby value to $2.49$ is 2.
• So, the value of Math.round($1.49$+1) is 2.

d. Math.round($1.49$)+1

• round returns the nearby int or long (as per the argument).
• Basically, it it used to round off the number.
• The datatype can be double or float.
• The nearby value to $1.49$ is 1.
• So, the value of Math.round($1.49$) is 1.
• Now, Math.round($1.49$)+1 $=1+1=2$.

e. Math.floor($5.6$)

• floor returns the largest integer which is less than or equal to the given argument.
• The datatype can be double.
• So, the value of Math.floor($5.6$) is $5.0$.

f. Math.ceil($4.1$)

• ceil returns the smallest integer which is greater than or equal to the given argument.
• The datatype can be double.
• So, the value of Math.ceil($4.1$) is $5.0$.

g. Math.min($3.4$,1)

• min returns the smallest numbers of the two given arguments.
• The datatype can be int, float, long, double.
• So, the value of Math.min($3.4$,1) is 1.
