Functions

This automatically generated page summarises the functions available in the expression language.used where data is needed for a parameter to a routine operation, an object delay time etc.

sqrt()

value = sqrt(value)

Returns square root of 'value'.

sqr()

value = sqr(value)

Returns 'value' multiplied by itself.

ceil()

value = ceil(value)

Returns largest integer not greater than 'value'.

floor()

value = floor(value)

Returns largest integer not greater than 'value'.

fabs()

value = fabs(value)

Returns removes negative sign if 'value' is negative.

round()

value = round(value)

Returns the nearest integer to 'value'.

trunc()

value = trunc(value)

Returns 'value' with the fraction trimmed off.

exp()

value = exp(value)

Returns mathematical 'e' to the power of 'value'.

ln()

value = ln(value)

Returns natural logarithm of 'value'.

log10()

value = log10(value)

Returns base 10 logarithm of 'value'.

pow10()

value = pow10(value)

Returns 10 to the power of 'value'.

pow2()

value = pow2(value)

Returns 2 to the power of 'value'.

cos()

value = cos(value)

Returns trigonometric cosine where 'value' is in radians.

sin()

value = sin(value)

Returns trigonometric sine where 'value' is in radians.

tan()

value = tan(value)

Returns trigonometric tangent where 'value' is in radians.

acos()

value = acos(value)

Returns inverse of cos() function.

asin()

value = asin(value)

Returns inverse of sin() function.

atan()

value = atan(value)

Returns inverse of tan() function. atan2 is more useful if you have an x,y point.

atan2()

value = atan2(x,y)

Returns angle in radians between x axis and (x,y) on cartesian graph.

hypot()

value = hypot(x,y)

Returns sqrt(x*x + y*y).

min()

value = min(val1,val2)

Returns minimum of 'val1' and 'val2'.

max()

value = max(val1,val2)

Returns maximum of 'val1' and 'val2'.

strlen()

integer-value = strlen(string)

Returns length of 'string'.

strleft()

string = strleft(string,count)

Returns leftmost 'count' characters from 'string'.

strmid()

string = strmid(string,pos,count)

Returns starting at 'pos' up to 'count' characters in 'string'.

strright()

string = strright(string,count)

Returns rightmost 'count' characters from 'string'.

strreverse()

string = strreverse(string)

Returns reversed order of characters in 'string'.

strupper()

string = strupper(string)

Returns 'string' converted to lowercase.

strlower()

string = strlower(string)

Returns 'string' converted to uppercase.

strcompare()

integer-value = strcompare(str1,str2[,casesensitive=0])

Returns 0 if 'str1' and 'str2' are the same, 1 if 'str1' has higher ascii-sort order, -1 if 'str1' has lower ascii-sort order. Default is to ignore case unless casesensitive is provided and is not zero.

strfind()

integer-value = strfind(str1,str2[,casesensitive=0])

Returns character where 'str2' first starts in 'str1' or 0 if not found.

strclean()

string = strclean(string)

Returns 'string' after leading spaces, trailing spaces, new lines and tabs have been removed. Any double quotes are made single.

strinsert()

string = strinsert(str1,str2,pos)

Returns 'str1 with str2 inserted before character at position 'pos'.

strdelete()

string = strdelete(string,pos,count)

Returns 'string' after deleteing 'count' characters starting at 'pos'.

strreplace()

string = strreplace(string,str1,str2[,casesensitive=0])

Returns 'string' after all occurances of 'str1' are replaced with 'str2'. Match is not casesensitive unless 'casesensitive' is non zero.

strchar()

integer-value = strchar(string,pos)

Returns ASCII code of character at 'pos' of 'string'.

strasc()

string = strasc(code)

Returns a single character string containing the given 8 bit ASCII character.
