Numeric operators

XBUILD accepts the following numeric operators:

Operator	Description
`+`	addition, adds two numbers. string concatenation, joins two strings. if given a string and a number, the string is converted into a number and then the two numbers are added.
`-`	subtraction, subtracts two numbers
`*`	multiplication, multiplies two numbers
`/`	division, divides two numbers
`%`	Modulo operation. Performs an integer division and returns the remainder. For example if `<ROT1-WIND>` returned a value of 380, then `[<ROT1-WIND>%360]` will return 20.
`tan(num)`	Computes the tangent of an angle (given in radians).
`sind(num)`	Computes the sine of an angle (given in degrees).
`cosd(num)`	Computes the cosine of an angle (given in degrees).
`tand(num)`	Computes the tangent of an angle (given in degrees).
`asin(num)`	Computes the arcsine (in radians) of a number.
`acos(num)`	Computes the arccosine (in radians) of a number.
`atan(num)`	Computes the arctangent (in radians) of a number.
`atan2(y,x)`	Computes the arctangent (in radians) of y/x.
`asind(num)`	Computes the arcsine (in degrees) of a number.
`fabs(num)`	Computes the absolute value of the number.
`in2mm(num)`	Converts inches to millimeters.
`anglexy(x,y)`	Computes the angle between the X-axis to the line between (0,0) and (x,y).
`acosd(num)`	Computes the arccosine (in degrees) of a number.
`atand(num)`	Computes the arctangent (in degrees) of a number.
`atan2d(y,x)`	Computes the arctangent (in degrees) of y/x.
`ceil(num)`	returns the nearest integer greater than or equal to a number.
`sqrt(num)`	Returns the square root of a number.
`mm2in(millimeters)`	Converts from millimeters to inches.
`exp(num)`	Returns e^x where e = 2.71828.
`log(num)`	Returns ln(x) where ln is the natural logarithm.
`log10(num)`	Returns the base-10 logarithm of a number.
`pow(base,power)`	Returns a base number raised to a power.
`degtorad(num)`	Returns an angle in radians as converted from degrees.
`radtodeg(num)`	Returns an angle in degrees as converted from radians.
`pi`	The mathematical value of pi to ten decimal places.
`radiusxy(x,y)`	Computes the distance from the origin to XY.

Example

If b = 12

The following line

[:a=b%10]

results in a = 2

The operation performed by the modulo operator is to return the remainder of a division. So a 12 divided by 10 will result in a remainder of 2. This can be used to restrict the angles between 0 and 360 on machines that require this limitation.
