5.指数运算,指数 exponent 为负数时 If you are raising things to negative exponents, you must specify a MathContext in BigDecimal.pow(int, MathContext) so it knows how much precision to use – otherwise, BigDecimal will try to compute it to infinite precision, which is not possible for some ...
The toEngineeringString() method may be used for presenting numbers with exponents in engineering notation, and the setScale method may be used for rounding a BigDecimal so it has a known number of digits after the decimal point. The digit-to-character mapping provided by Character.forDigit is...
The doubler parameters are exponents of powers of 2. For example, if the xyDoubler = 2, then the XY grid resolution of the output spatial reference is 4 times the input grid resolution (16 new grid cells cover 1 old grid cell). The grid also is translated so it remains centered abo...

The java.lang.Math class defines the PI constant and many static methods, including methods for calculating sines, cosines, tangents, square roots, maxima, minima, exponents, and many more. For example, public static final double PI = 3.141592653589793; public static double cos(double a) { ...
To prefix positive exponents with a localized plus sign, specify '+' between the exponent and the digits: "0.###E+0" will produce formats "1E+1", "1E+0", "1E-1", etc. (In localized patterns, use the localized plus sign rather than '+'.) The minimum number of integer digits...
