MetaFun - Pragma ADE

212
decr(x,n) decrement x by n
incr(x,n) increment x by n
max(a,b,..) return the maximum value in the list
min(a,b,..) return the minimum value in the list
The min and max funtions can be applied to numerics as well as strings.
The following functions are related to strings:
oct s string representation of an octal number
hex s string representation of a hexadecimal number
str s string representation for a suffix
ASCII s ASCII value of the first character
char x character of the given ASCII code
decimal x decimal representation of a numeric
With substring (i,j) of s you can filter the substring bounded by the given indices from the
given string.
In METAFUN we provide a few more functions (you can take a look in mp-tool.mp to see how they
are defined. You need to be aware of very subtle rounding errors. Normally these only show up
when you reverse an operation. This is a result from mapping to and from internal quantities.
sqr(x) x 2
log(x) log(x)
ln(x) ln(x)
exp(x) e x
pow(x, p) x p
inv(x) 1/x
The following sine and cosine functions take radians instead of angles in degrees.
sin(x) asin(x) invsin(x)
cos(x) acos(x) invcos(x)
There are no tangent functions, so we provide both the radian and degrees versions:
tan(x) tand(x)
cot(x) cotd(x)
Here are a couple of hyperbolic functions.
sinh(x) asinh(x)
cosh(x) acosh(x)
We end with a few additional string converters.
ddecimal x decimal representation of a pair
dddecimal x decimal representation of a color
condition x string representation of a boolean
