exceptInf back to summary

exceptInf	back to summary
private static double exceptInf(double result, double arg) Turn an infinite result into a thrown `OverflowError`, a math range error, if the original argument was not itself infinite. Use as: public static double cosh(double v) { return exceptInf( Math.cosh(v), v); } Note that the original function argument is also supplied to this method. Most Java math library methods do exactly what we need for Python, but some return an infinity when Python should raise `OverflowError`. This is a brief way to change that. Parameters result:double to return (if we return) arg:double to include in check Returns:double result if `arg` was infinite or `result` was not infinite Exceptions PyException: `ValueError` if `result` was infinite and `arg` was not infinite

private static double exceptInf(double result, double arg)

Turn an infinite result into a thrown OverflowError, a math range error, if the original argument was not itself infinite. Use as:

public static double cosh(double v) { return exceptInf( Math.cosh(v), v); }

Note that the original function argument is also supplied to this method. Most Java math library methods do exactly what we need for Python, but some return an infinity when Python should raise OverflowError. This is a brief way to change that.

Parameters

result:double: to return (if we return)
arg:double: to include in check

Returns:double

result if arg was infinite or result was not infinite

Exceptions

PyException:: ValueError if result was infinite and arg was not infinite

exceptNaN back to summary

exceptNaN	back to summary
private static double exceptNaN(double result, double arg) throws PyException Turn a `NaN` result into a thrown `ValueError`, a math domain error, if the original argument was not itself `NaN`. Use as: public static double asin(double v) { return exceptNaN(Math.asin(v), v); } Note that the original function argument is also supplied to this method. Most Java math library methods do exactly what we need for Python, but some return NaN when Python should raise `ValueError`. This is a brief way to change that. Parameters result:double to return (if we return) arg:double to include in check Returns:double result if `arg` was `NaN` or `result` was not `NaN` Exceptions PyException: `ValueError` if `result` was `NaN` and `arg` was not `NaN`

private static double exceptNaN(double result, double arg) throws PyException

Turn a NaN result into a thrown ValueError, a math domain error, if the original argument was not itself NaN. Use as:

public static double asin(double v) { return exceptNaN(Math.asin(v), v); }

Note that the original function argument is also supplied to this method. Most Java math library methods do exactly what we need for Python, but some return NaN when Python should raise ValueError. This is a brief way to change that.

Parameters

result:double: to return (if we return)
arg:double: to include in check

Returns:double

result if arg was NaN or result was not NaN

Exceptions

PyException:: ValueError if result was NaN and arg was not NaN
