=== Functions ===
==== <code><big>ABS (n<numeric expression>)</big></code> ====
: ''BASIC 1.0 & 1.1''
: '''FUNCTION''': Returns the ABSolute value of the given numeric expression (n). This means that negative numbers are returned as positive.
</pre>
==== <code><big>ASC (s<string expression>)</big></code> ====
: ''BASIC 1.0 & 1.1''
: '''FUNCTION''': Returns the numeric value of the first character in the <string expression> (s).
120
</pre>
==== <code><big>ATN (n<numeric expression>)</big></code> ====
: ''BASIC 1.0 & 1.1''
: '''FUNCTION''': Calculates the Arc-TaNgent of the <numeric expression> (n) to a real number ranging from -PI/2 to +PI/2 of the value specified.
0.785398163
</pre>
==== <code><big>BIN$ (i1<unsigned integer expression>,[i2<integer expression>])</big></code> ====
: ''BASIC 1.0 & 1.1''
: '''FUNCTION''': Produces a string of BINary digits respresenting the value of the <unsigned integer expression>, using the number of binary digits instruced by the second <integer expression> (in the range of 0 to 16). If the number of digits instructed is too great, the resulting expression will be filled with leading zeros; if the number of digits instructed is too small, the resulting expression will NOT be shortened to the instructed number of digits, but will produced in as many digits as are required.
01000000
</pre>
==== <code><big>CHR$ (n<numeric expression>)</big></code> ====
: ''BASIC 1.0 & 1.1''
: '''FUNCTION''': Converts an <integer expression> in the range 0 to 255, to its CHaRacter $tring equivalent, using the AMSTRAD character set shown in the ASCII table or e.g. in the manual part 3.
===============================================================================
</PRE>
==== <code><big>CINT (n<numeric expression>)</big></code> ====
: ''BASIC 1.0 & 1.1''
: '''FUNCTION''': Returns the value of the <numeric expression> (n), Converting it to a rounded INTeger in the range -32768 to 32767.
60 PRINT a$
</pre>
==== <code><big>COS (n<numeric expression>)</big></code> ====
: ''BASIC 1.0 & 1.1''
: '''FUNCTION''': Calculates the COSinus of the <numeric expression> (n).
0.707106781
</pre>
==== <code><big>CREAL (n<numeric expression>)</big></code> ====
: ''BASIC 1.0 & 1.1''
: '''FUNCTION''': Returns the value of the <numeric expression> (n), Converting it to REAL.
3.14159265
</pre>
==== <code><big>DEC$(n<numeric expression>, <formattemplate>)</big></code> ====
: ''BASIC 1.1''
: '''FUNCTIION''': Returns a DECimal string representation of the <numeric expression> (n), using the specified <format template> to control the print format of the resulting string.
1050 END
</pre>
==== <code><big>EXP (i<integer expression>)</big></code> ====
: ''BASIC 1.0 & 1.1''
: '''FUNCTION''': Calculates 'E' to the power given in the <numeric expression> (i), where 'E' is approximately 2,7182818-the number whose natural logarithm is 1.
968.743625
</pre>
==== <code><big>FIX (n<numeric expression>)</big></code> ====
: ''BASIC 1.0 & 1.1''
: '''FUNCTION''': Unlike CINT, FIX merely removes the part of the numeric expression, to the right of the decimal point, and leaves an integer result, rounding towards zero.
9
</pre>
==== <code><big>FRE (n<numeric expression>/st<string expression>)</big></code> ====
: ''BASIC 1.0 & 1.1''
: '''FUNCTION''': Establishes how much FREe memory remains unused by BASIC. The form FRE("") forces a 'GARBAGE COLLECTION' before returning a value for available space.
PRINT FRE("")
</pre>
==== <code><big>HEX$ (i1<unsigned integer expression>, i2<field width>)</big></code> ====
: ''BASIC 1.0 & 1.1''
: '''FUNCTION''': Produces a $tring of HEXadecimal digits representing the value of the <unsigned integer expression>, using the number of hexadecimal digits instructed by the <field width> (in the range 0 to 16). If the number of digits instructed is too great, the resulting expression will be filled with leading zeros; if the number of digits instructed is too small, the resulting expression will NOT be shortened to the instructed number of digits, but will be produced in as many digits as are required.
42619
</pre>
==== <code><big>INKEY (i<integer expression>)</big></code> ====
: ''BASIC 1.0 & 1.1''
: '''FUNCTION''': INterrogates the KEYboard to report which keys are being pressed. The keyboard is scanned every 0.02 (1/50) second.
