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.

- - 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\n". -
- - 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)
