Slow delivery leads to missed opportunities, innovation is stalled due to architectural complexities, and engineering resources are exceedingly expensive. Orkes is the leading workflow orchestration platform built to enable teams to transform the way they develop, connect, and deploy applications, microservi...
sqrt(double a) Returns the correctly rounded positive square root of a double value. static double tan(double a) Returns the trigonometric tangent of an angle. static double tanh(double x) Returns the hyperbolic tangent of a double value. static double toDegrees(double angrad) Converts an angl...
NegativeArraySizeException - if the capacity argument is less than 0.StringBuilder public StringBuilder(String str) Constructs a string builder initialized to the contents of the specified string. The initial capacity of the string builder is 16 plus the length of the string argument. Parameters: st...
An unsigned integer maps the values usually associated with negative numbers to positive numbers larger than MAX_VALUE. The characters in the string must all be digits of the specified radix (as determined by whether Character.digit(char, int) returns a nonnegative value), except that the first...
In an unsigned conversion to an int, the high-order 16 bits of the int are zero and the low-order 16 bits are equal to the bits of the short argument. Consequently, zero and positive short values are mapped to a numerically equal int value and negative short values are mapped to an ...

Converts this BigDecimal to a float. This conversion is similar to the narrowing primitive conversion from double to float as defined in The Java Language Specification: if this BigDecimal has too great a magnitude to represent as a float, it will be converted to Float#NEGATIVE_INFINITY or Floa...
