All functions have following syntax: FUNCTION_NAME(FUNCTION_ARGUMENT_1, FUNCTION_ARGUMENT_2, ...). Nesting functions is allowed. Any math expression as argument is allowed.

• abs() - returns absolute value of argument, ex. abs(x)
• acos() - returns arc cosine of argument, ex. acos(x)
• asin() - returns arc sine of argument, ex. asin(x)
• atan() - returns arc tangent of argument, ex. atan(x)
• avg() - calculates the average of arguments, ex. avg(x,y,z)
• cos() - returns cosine of argument, ex. cos(x)
• cosh() - returns hyperbolic cosine of argument, ex. cosh(x)
• exp() - calculates the exponent of e, ex. exp(x)
• fmod() - returns the floating point remainder (modulo) of the division of the arguments, ex. fmod(x,y)
• log() - returns natural logarithm of argument, ex. log(x)
• log10() - returns base-10 logarithm of argument, ex. log10(x)
• pow() - returns base raised to the power of exp, ex. pow(base,exp)
• sin() - returns sine of argument, ex. sin(x)
• sinh() - returns hyperbolic sine of argument, ex. sinh(x)
• tan() - returns tangent, ex. tan(x)
• tanh() - returns hyperbolic tangent of argument, ex. tanh(x)
• ceil() - returns fraction rounded up, ex. ceil(x)
• floor() - returns fraction rounded down, ex. floor(x)
• hypot() - calculates the length of the hypotenuse of a right-angle triangle, ex. hypot(x)
• sum() - calculates the sum of arguments, ex. sum(x,y,z)
• sqr() - calculates square root of argument, ex. sqr(x)
