Description |
Example |
| double cos ( double x ) |
trigonometric sine of x (x is in radians: to convert degrees to radians use toRadians() ) |
cos ( 0.0 ) = 1.0 |
int max ( int x, int y )
long max ( long x, long y) |
larger value of x and y
(also version for float values) |
max ( 2.3, 12.8 ) = 12.8
max ( -2.4, -11.7) = -2.4 |
int min ( int x, int y )
long min ( long x, long y ) |
smaller value of x and y
(also version for float values) |
min ( 2.3, 12.8 ) = 2.3
min ( -2.4, -11.7 ) = -11.7 |
| double pow ( double x, double y ) |
x raised to power y (xy) |
pow ( 2.0, 5 ) = 32
pow ( 16, 0.5 ) = 4 |
| long round( double x ) |
closest long to x |
round ( 4.3 ) = 4
round ( -9.7 ) = -10 |
| double sin ( double x) |
trigonometric sine of x (x is in radians: to convert degrees to radians use toRadians() ) |
sin ( 0.0 ) = 0.0 |
| double sqrt ( double x ) |
square root of x |
sqrt ( 16.0 ) = 4
sqrt ( 2.0 ) = 1.14142... |
| double tan ( double x ) |
trigonometric cosine of x (x is in radians: to convert degrees to
radians use toRadians() ) |
tan ( 0.0 ) = 0.0 |
| double toRadians (double x) |
Converts an angle, x, measured in degrees to the equivalent angle
measured in radians. |
toRadians ( 0. 0 ) = 0.0
toRadians ( 90.0 ) = 1.570..
toRadians ( 180.0 ) = 3.14.. |
| PI |
not a method but a constant (or field as called in Java) |
3.14159265358... |
| Note: to use any of these you need to use the
format Math.PI, Math.sin(x), etc. |
