27 DEFINITION MODULE ConvStringLong
;
29 FROM DynamicStrings
IMPORT String
;
33 RealToFloatString - converts a real with, sigFigs, into a string
34 and returns the result as a string.
37 PROCEDURE RealToFloatString (real
: LONGREAL; sigFigs
: CARDINAL) : String
;
41 RealToEngString - converts the value of real to floating-point
42 string form, with sigFigs significant figures.
43 The number is scaled with one to three digits
44 in the whole number part and with an exponent
45 that is a multiple of three.
48 PROCEDURE RealToEngString (real
: LONGREAL; sigFigs
: CARDINAL) : String
;
52 RealToFixedString - returns the number of characters in the fixed-point
53 string representation of real rounded to the given
54 place relative to the decimal point.
57 PROCEDURE RealToFixedString (real
: LONGREAL; place
: INTEGER) : String
;
