HOC(1) General Commands Manual HOC(1)NAME
hoc - interactive floating point language
SYNOPSIS
hoc [ file ... ] [ -e expression ]
DESCRIPTION
Hoc interprets a simple language for floating point arithmetic, at about the level of BASIC, with C-like syntax and functions.
The named files are read and interpreted in order. If no file is given or if file is hoc interprets the standard input. The -e option
allows input to hoc to be specified on the command line, to be treated as if it appeared in a file.
Hoc input consists of expressions and statements. Expressions are evaluated and their results printed. Statements, typically assignments
and function or procedure definitions, produce no output unless they explicitly call print.
Variable names have the usual syntax, including the name by itself contains the value of the last expression evaluated. The variables E,
PI, PHI, GAMMA and DEG are predefined; the last is 59.25..., degrees per radian.
Expressions are formed with these C-like operators, listed by decreasing precedence.
^ exponentiation
! - ++ --
* / %
+ -
> >= < <= == !=
&&
||
= += -= *= /= %=
Built in functions are abs, acos, asin, atan (one argument), cos, cosh, exp, int, log, log10, sin, sinh, sqrt, tan, and tanh. The function
read(x) reads a value into the variable x and returns 0 at EOF; the statement print prints a list of expressions that may include string
constants such as "hello
".
Control flow statements are if-else, while, and for, with braces for grouping. Newline ends a statement. Backslash-newline is equivalent
to a space.
Functions and procedures are introduced by the words func and proc; return is used to return with a value from a function.
EXAMPLES
func gcd(a, b) {
temp = abs(a) % abs(b)
if(temp == 0) return abs(b)
return gcd(b, temp)
}
for(i=1; i<12; i++) print gcd(i,12)
