Java Summary: Math Class

In this section we will study about the Match class of Java API.

Some basic math functions can be found in the Math class. The StrictMath class (not described here) may produce less accurate results and be slower, but will produce absolutely identical results, bit for bit, on all machines.

Don't use StrictMath unless you need this very specific kind of portability.

If you need numbers that exceed the range of long, use java.math.BigInteger.

If you need to do exact decimal arithmetic, use java.math.BigDecimal, which gives complete control over precision and rounding, eg for financial calculations. Assume following declarations

float f;
double d, d1, d2;
double ar;  // angle in radians.
x is any of int, long, float, or double.
