Maths

Where Is Maths Used ?

When you do Variable Set and click the Do Maths checkbox
With the If action, if you select a mathematical comparison like < or =
With individual action conditions when a mathematical comparison is selected

What's Available

Tasker uses the MathEval library by Lawrence PC Dol.

Operators

+ - * / - the basic operators
% - modulus
^ - power

Constants

E - the base of the natural logarithms
EUL - Euler's Constant
LN2 - log of 2 base e
LN10 - log of 10 base e
LOG2E - log of e base 2
LOG10E - log of e base 10
PHI - the golden ratio
PI - the ratio of the circumference of a circle to its diameter

Functions

Trigonometric functions expect a value in radians.

Functions take their argument in parenthesis e.g. sin(torad((90))

abs - absolute value
acos - arc cosine; the returned angle is in the range 0.0 through pi
asin - arc sine; the returned angle is in the range -pi/2 through pi/2
atan - arc tangent; the returned angle is in the range -pi/2 through pi/2
cbrt - cube root
ceil - smallest value that is greater than or equal to the argument and is an integer
cos - trigonometric cosine
cosh - hyperbolic cosine
exp - Euler's number e raised to the power of the value
expm1 - ex-1
floor - largest value that is less than or equal to the argument and is an integer
getExp - unbiased exponent used in the representation of val
log - natural logarithm (base e)
log10 - base 10 logarithm
log1p - natural logarithm of (val+1)
nextup - floating-point value adjacent to val in the direction of positive infinity
round - closest 64 bit integer to the argument
roundhe - double value that is closest in value to the argument and is equal to a mathematical integer, using the half-even rounding method.
signum - signum function of the argument; zero if the argument is zero, 1.0 if the argument is greater than zero, -1.0 if the argument is less than zero
sin - trigonometric sine
sinh - hyperbolic sine
sqrt - correctly rounded positive square root
tan - trigonometric tangent
tanh - hyperbolic tangent
todeg - converts an angle measured in radians to an approximately equivalent angle measured in degrees
torad - converts an angle measured in degrees to an approximately equivalent angle measured in radians
ulp - size of an ulp of the argument
