AthleteMonitoring use a powerful mathematical library that includes many functions that you can use to calculate test results. To add a function in a formula, simply type it's name in the Formula box. For example, to create a ratio that always returns an absolute number, you can use the 'abs' function like this : abs(((abdr/addr)-1)*100)

abdr= symbol associated with first measure

addr= symbol associated with second measure

 Function Explanation abs Absolute value acos Arc cosine -- output in radians. acosh Inverse hyperbolic cosine -- output in radians. asin Arc sine -- output in radians. asinh Inverse hyperbolic sine.-- output in radians. atan2 Arc tangent of two variables -- pass in two values like (y, x), and you'll get the atan(y/x), adjusted to the proper quadrant. (Note: The variables are in the reverse order to atan2(x,y) in Excel) Output is radians. atan Arc tangent -- output in radians. atanh Inverse hyperbolic tangent-- output in radians. bindec Binary to decimal ceil Round fractions up cos Cosine -- in radians!!! Convert your degree measurement to radians before you take the cos of it. cosh Hyperbolic cosine -- in radians!!! Convert your degree measurement to radians before you take the cosh of it. decbin Decimal to binary decoct Decimal to octal deg2rad Converts the number in degrees to the radian equivalent exp Calculates the exponent of e expm1 Returns exp(number) - 1, computed in a way that is accurate even when the value of number is close to zero floor Round fractions down fmod Returns the floating-point modulus of two numbers - i.e. the remainder when the first is divided by the second. is_finite Finds whether a value is a legal finite number log10 Base-10 logarithm log1p Returns log(1 + number), computed in a way that is accurate even when the value of number is close to zero log Natural logarithm (ln) max Find highest value min Find lowest value octdec Octal to decimal pi() Get value of pi - the function does not take an argument, like in Excel. pow (numberToRaise, NumberRaisedTo) power (numberToRaise, NumberRaisedTo) Exponential expression rad2deg Converts the radian number to the equivalent number in degrees rand Generate a random integer rand_int Generate a random integer rand_float Generate a random float round Rounds a float sin Sine -- in radians!!! Convert your degree measurement to radians before you take the sin of it. sinh Hyperbolic sine -- in radians!!! Convert your degree measurement to radians before you take the sinh of it. sqrt Square root tan Tangent -- in radians!!! Convert your degree measurement to radians before you take the tan of it. tanh Hyperbolic tangent -- in radians!!! Convert your degree measurement to radians before you take the tanh of it.
