math() Function

Introduced in version 1.4.0.5
This is NOT a single MapTool function but a collection of math functions in MapTool.

Important Note: Some of these functions have similar versions that don't have the math. prefix. These functions may differ slightly from those in implementation and output. For instance, most of these functions return a floating-point number (e.g.: 3.0), so you may find it helpful to surround them with round(), floor(), or ceiling().

Usage

Numbers:
[r:val = math.pi()]
[r:val = math.e()]

Trigonomotry:
[r:val = math.acos(degrees)]
[r:val = math.acos_r(radians)]
[r:val = math.asin(degrees)]
[r:val = math.asin_r(radians)]
[r:val = math.atan(degrees)]
[r:val = math.atan_r(radians)]
[r:val = math.atan2(degrees)]
[r:val = math.atan2_r(radians)]
[r:val = math.cos(degrees)]
[r:val = math.cos_r(num)]
[r:val = math.sin(degrees)]
[r:val = math.sin_r(num)]
[r:val = math.tan(degrees)]
[r:val = math.tan_r(num)]
[r:val = math.toDegrees(num)]
[r:val = math.toRadians(degrees)]

Power and root:
[r:val = math.sqrt(num)]
[r:val = math.squareroot(num)]
[r:val = math.cbrt(num)]
[r:val = math.cuberoot(num)]
[r:val = math.pow(num1,num2)]

Logarithmic
[r:val = math.log(num)] (this is the log to base e)
[r:val = math.log10(num)]

Pythagorean:
[r:val = math.hypot(num1, num2)]
[r:val = math.hypotenuse(num1, num2)]

Simple operations
[r:val = math.abs(num)]
[r:val = math.ceil(num)]
[r:val = math.floor(num)]
[r:val = math.isEven(num)]
[r:val = math.isInt(num)]
[r:val = math.isOdd(num)]
[r:val = math.max(num1, num2, num2, etc.)]
[r:val = math.min(num1, num2, num2, etc.)]
[r:val = math.mod(dividend, divisor)]

Examples

abs

[r:val =  math.abs(-3)]

Returns: 3.0

mod

Returns the result of the modulo operation between the two numbers, which represents the remainder after a division operation.

[r: math.mod(14,6)]

Returns 2

[r: math.mod(10,5)]

Returns 0

[r: math.mod(-13,4)]

Returns -1

pow

[r:val =  math.pow(2,3)]
Returns: 8.0
