- abs
- absolute value
- acos
- arccosine (the inverse of the cosine - produces such angle that the cosine of it has the given value)
- acosh
- inverse hyperbolic cosine
- asin
- arcsine
- asinh
- inverse hyperbolic sine
- atan or atg
- arctangent
- atan2 or atg2
- arctangent that takes two arguments: atan2(y, x) denotes arctangent of y/x.
The signs of arguments y and x are taken into account, so that a result in the range -π/2 through π/2
is produced.
- atanh or atgh
- inverse hyperbolic tangent
- besj0, besj1, besy0, besy1
- Bessel functions J0, J1, Y0, Y1
(they take argument always in radians, regardlessly of the selected angle unit)
- ceil
- round to the nearest integer greater or equal to the given value
- cos
- cosine
- cosh
- hyperbolic cosine
- cot
- cotangent? no such function here! Make use of the fact that cot(x) = 1 / tan(x)
- erf
- Gauss error function
- erfc
- complementary error function erfc(x) = 1 - erf(x)
- exp
- exponential function, exp(x) = ex
- floor
- round to the nearest integer less or equal to the given value
- gamma
- gamma function
- inverf
- Inverse function of the error function erf
- invnorm
- Inverse function of the cumulative Gaussian distribution function
- ln
- Natural logarithm (to the base e)
- log
- Common logarithm (to the base 10)
- norm
- Cumulative Gaussian distribution function (probability that a random variable will be
less or equal to the given value)
- sgn
- Sign of a number - for negative numbers it is -1, for zero 0, for positive numbers +1
- sin
- sine
- sinh
- hyperbolic sine
- sqrt
- square root
- tan or tg
- tangent
- tanh or tgh
- hyperbolic tangent
