## Mathematical functions

We are currently rewriting our product documentation. It isn’t complete yet but growing. An alphabetical overview of the NX script (mathematical) functions is ready for your review. Check it out!

1234: Enters a constant number.

Addition: the addition (a + b) results in

- (Number + Number) the sum of a and b, if both are numeric values,
- (Text + …) or (… + Text) a compound text of a and b,
- (Date + Number) the date a increased by b days,
- (Date + Time interval) a date/time, that is date a increased by b,
- (Time + Number) the time a increased by b milliseconds,
- (Time + Time) the sum of time a and time b,
- (Time + Time interval) the time a increased by the time interval b,
- (Date/Time + Number) the date/time a increased by b milliseconds,
- (Date/Time + Time interval) the date/time a increased by the time interval b,
- (Time interval + Number) the time interval a increased by b milliseconds,
- (Time interval + Time interval) the sum of both time intervals a and b.

Subtraction: the subtraction (a – b) results in

- (Number – Number) the Number a – b,
- (Date – Date) the time interval from b to a,
- (Time/Date – Time/Date) the time interval from b to a,
- Subtract b from a, see: addition

Multiplication: multiplies (a * b)

- (Number * Number) the number a * b,
- (Time interval * Number) the time interval a * b,

Division: divides (a / b)

- (Number / Number) the number a / b,
- (Time interval / Number) the time interval a / b,

√{} (x) calculates the square root of x.

2

(x) calculates the square of x.

`pow(x, y)`

calculates the power of y to the base of x, in other words, x to the power of y.

e

( x ) calculates e to the power of x.

log10( x ) calculates the logarithm of x to the base 10.

ln( x ) calculates the natural logarithm of x, that is, to the base of e.

Logarithms to the base of y can be calculated with ln( x ) / ln( y ).

sin( x ) calculates the sinus of x (as a radian measure).

cos( x ) calculates the cosine of x (as a radian measure).

tan( x ) calculates the tangent of x (as a radian measure).

asin( x ) calculates the arc sinus of x (as a radian measure).

acos( x ) calculates the arc cosine of x (as a radian measure).

atan( x ) calculates the arc tangent of x (as a radian measure).

atan

2

( x ) calculates the square arc tangent of x (as a radian measure).

round( x ) rounds x to the nearest whole number.

ceil( x ) rounds x up.

floor( x ) rounds x down.

sign( x ) results in -1, if x is negative, else 1.

absolute( x ) calculates the absolute amount of x, that is, x without a sign.

Example: absolute( -10 ) = absolute( 10 ) = 10.
