Predefined Methods Class Math- Java Sample Program

class Math (Package: java.lang)

Example:

abs(-67) returns the value 67

abs(35) returns the value 35

abs(-75.38) returns the value 75.38

ceil(x)
x is of type double. Returns a value of type double, which is the
smallest integer value that is not less than x.
Example: ceil(56.34) returns the value 57.0

exp(x)
x is of type double. Returns ex, where e is approximately
2.7182818284590455.
Example: exp(3) returns the value 20.085536923187668

floor(x)
x is of type double. Returns a value of type double, which is the
largest integer value less than x.
Example: floor(65.78) returns the value 65.0

log(x)
x is of type double. Returns a value of type double, which is the
natural logarithm (base e) of x.
Example: log(2) returns the value 0.6931471805599453

log10(x)
x is of type double. Returns a value of type double, which is the
common logarithm (base 10) of x.
Example: log10(2) returns the value 0.3010299956639812

max(x, y)
Returns the larger of x and y. If x and y are of type int, it returns a
value of type int; if x and y are of type long, it returns a value of type
long; if x and y are of type float, it returns a value of type float;
if x and y are of type double, it returns a value of type double.
Example: max(15, 25) returns the value 25

max(23.67, 14.28) returns the value 23.67

max(45, 23.78) returns the value 45.00

min(x, y)
Returns the smaller of x and y. If x and y are of type int, it returns a
value of type int; if x and y are of type long, it returns a value of type
long; if x and y are of type float, it returns a value of type float;
if x and y are of type double, it returns a value of type double.
Example: min(15, 25) returns the value 15

min(23.67, 14.28) returns the value 14.28

min(12, 34.78) returns the value 12.00

pow(x, y)
x and y are of type double. Returns a value of type double, which is xy.
Example: pow(2.0, 3.0) returns the value 8.0

pow(4, 0.5) returns the value 2.0

round(x)
Returns a value which is the integer closest to x.
Example: round(24.56) returns the value 25

round(18.35) returns the value 18
