|
Is Not-A-Number. Returns whether x is a NaN (Not-A-Number) value. The NaN values are used to identify undefined or non-representable values for floating-point elements, such as the square root of negative numbers or the result of 0/0.
|
|
Compute arc cosine. Returns the principal value of the arc cosine of x, expressed in radians. In trigonometrics, arc cosine is the inverse operation of cosine.
|
|
Returns the principal value of the arc sine of x, expressed in radians. In trigonometrics, arc sine is the inverse operation of sine.
|
|
Compute arc tangent. Returns the principal value of the arc tangent of x, expressed in radians. In trigonometrics, arc tangent is the inverse operation of tangent. Notice that because of the sign ambiguity, the function cannot determine with certainty in which quadrant the angle falls only by its tangent value.
|
|
Compute arc tangent with two parameters. Returns the principal value of the arc tangent of y/x, expressed in radians. To compute the value, the function takes into account the sign of both arguments in order to determine the quadrant. If both arguments passed are zero, a domain error occurs.
|
|

|
|
Compute cosine. Returns the cosine of an angle of x radians.
|
|
Compute hyperbolic cosine. Returns the hyperbolic cosine of x radians.
|
|
Update the CRC7 for the data buffer.
|
|
Compute exponential function. Returns the base-e exponential function of x, which is e raised to the power x: e^x.
|
|
Returns the absolute value of x: |x|.
|
|
Round down value. Rounds x downward, returning the largest integral value that is not greater than x.
|
|

|
|
Compute natural logarithm. Returns the natural logarithm of x. The natural logarithm is the base-e logarithm: the inverse of the natural exponential function (exp). For common (base-10) logarithms, see log10.
