Functions

abs

Usage:

Computes and returns an absolute value for the number specified by the parameter val.

Example:

echo abs(-123456)

echo abs(123456)

Result:

123456

123456

acos

Usage:

Computes and returns the arc cosine of the number specified in the parameter val, in radians.

Example:

• echo acos(0.75)

Result:

• (City Name) - 0.7227342478134157 (City Name) - Script stopped

asin

Usage:

Computes and returns the arc sine for the number specified in the parameter val, in radians.

Example:

• echo asin(0.75)

Result:

• (City Name) - 0.848062078981481 (City Name) - Script stopped

atan

Usage:

Computes and returns the value, in radians, of the angle whose tangent is specified in the parameter val.

Example:

• echo atan(7)

Result:

• (City Name) - 1.4288992721907328 (City Name) - Script stopped

atan2

Usage:

Returns a string comprising the characters represented by the Unicode character codes in the parameters.

Example:

• echo atan2(7,3)

Result:

• (City Name) - 1.1659045405098132 (City Name) - Script stopped

ceil

Usage:

Returns the ceiling of the specified number or expression. Basically this means return the number rounded up to next whole number

Example:

echo ceil(4.1)

Result:

• (City Name) - 5 (City Name) - Script stopped

cos

Usage:

Computes and returns the cosine of the specified angle in radians.

Example:

• echo cos(7)

Result:

• (City Name) - 0.7539022543433046 (City Name) - Script stopped

exp

Usage:

Returns the value of the base of the natural logarithm (e), to the power of the exponent specified in the parameter x.

Example:

• echo exp(7)

Result:

• (City Name) - 1096.633158428458 (City Name) - Script stopped

floor

Usage:

Returns the floor of the number or expression specified in the parenthesis... Floor is the whole number part, without the decimals. Basically means chop the decimal portion of the number off.

Example:

echo floor(1234.56)

Result:

• (City Name) - 1234 (City Name) - Script stopped

pow

Usage:

Computes and returns base to the power of pow.

Example:

• echo pow(7, 3)

Result:

• (City Name) - 343 (City Name) - Script stopped

max

Usage:

Evaluates val1 and val2 (or more values) and returns the largest value.

Example:

echo max( city.troop.scouter, 100k )

Result:

If city.troop.scouter (the current number of scouts in the city) < 100k, then max( city.troop.scouter, 100k ) will return the number of scouts in city. If city.troop.scouter >= 100k then it will return 100000

min

Usage:

Evaluates val1 and val2 (or more values) and returns the smallest value.

Example:

echo min(city.resource.food.amount,99999999)

Result:

this will return whichever is smaller, 99,999,999 or the current amount of food in the city

random

Usage:

Returns a pseudo-random number n, where 0 <= n < 1.

Example:

echo round(random()*10)

Result:

a random number between 0 and 9

round

Usage:

Rounds the value of the parameter val up or down to the nearest integer and returns the value. Optional argument to specify precision (or number of decimal places).

Example:

echo round(6.66666666666666666666)

echo round(6.66666666666666666666,1)

echo round(6.66666666666666666666,2)

echo round(6.66666666666666666666,3)

Result:

7

6.7

6.67

6.667

sin

Usage:

Computes and returns the sine of the specified angle in radians.

Example:

• echo sin(3)

Result:

• (City Name) - 0.1411200080598672 (City Name) - Script stopped

sqrt

Usage:

Computes and returns the square root of the specified number.

Example:

• echo sqrt(16)

Result:

• (City Name) - 4 (City Name) - Script stopped

tan

Usage:

Computes and returns the tangent of the specified angle.

Example:

• echo tan(4)

Result:

• (City Name) - 1.1578212823495775

(City Name) - Script stopped
