- acosh
- double acosh(
double fValue );
virtual abstract const volatile template static inline C-linkage NO NO NO NO NO NO YES NO
- Summary
- A wrapper around rtl_math_acosh.
- approxAdd
- double approxAdd(
double a, double b );
virtual abstract const volatile template static inline C-linkage NO NO NO NO NO NO YES NO
- Summary
- Add two values.
- Description
- If signs differ and the absolute values are equal according to approxEqual() the method returns 0.0 instead of calculating the sum. If you wanted to sum up multiple values it would be convenient not to call approxAdd() for each value but instead remember the first value not equal to 0.0, add all other values using normal + operator, and with the result and the remembered value call approxAdd().
- approxCeil
- double approxCeil(
double a );
virtual abstract const volatile template static inline C-linkage NO NO NO NO NO NO YES NO
- Summary
- ceil()method taking approxValue() into account.
- Description
- Use for expected integer values being calculated by double functions.
- approxEqual
- bool approxEqual(
double a, double b );
virtual abstract const volatile template static inline C-linkage NO NO NO NO NO NO YES NO
- Summary
- Test equality of two values with an accuracy of the magnitude of the given values scaled by 2^-48 (4 bits roundoff stripped).
- ATTENTION!
- approxEqual( value!=0.0, 0.0 ) _never_ yields true.
- approxFloor
- double approxFloor(
double a );
virtual abstract const volatile template static inline C-linkage NO NO NO NO NO NO YES NO
- Summary
- floor()method taking approxValue() into account.
- Description
- Use for expected integer values being calculated by double functions.
- approxSub
- double approxSub(
double a, double b );
virtual abstract const volatile template static inline C-linkage NO NO NO NO NO NO YES NO
- Summary
- Substract two values (a-b).
- Description
- If signs are identical and the values are equal according to approxEqual() the method returns 0.0 instead of calculating the substraction.

- If a value is a valid argument for sin(), cos(), tan().
- Description
- IEEE 754 specifies that absolute values up to 2^64 (=1.844e19) for the radian must be supported by trigonometric functions. Unfortunately, at least on x86 architectures, the FPU doesn't generate an error pattern for values >2^64 but produces erroneous results instead and sets only the "invalid operation" (IM) flag in the status word :-( Thus the application has to handle it itself.
