Fct_Float_2

Convert a floating point value to a text string.

Syntax

char * Fct_Float_2_Surf(

double surface,

char *units=NULL,

char *str=NULL

) ;

Parameters

surface

Original floating point value of the surface (in mm²).

units

If present, the string pointed by this variable will contain the units used for the surface.

str

Optional pointer to a text buffer that will contain the results. If NULL (the default) the result text string will be a static string locate inside the function.

Return value

This function return a pointer to a text string containing a text representation of the floating point value "val"

Remarks

If you do not specify a target string and you call the function twice, the second call to the function will overwrite the value returned by the first call since they will share the same static variable.

Requirements

Header:

sliceO_include.hpp

Library:

sliceO_Structures.lib

Example

...

// --- if Surfaces: gives out surface and volume ---

if ( mov->Flag & GEOM_POLY ) {

char str[40], units[10] ;

float surf = Movie_Surface( mov ) ;

Fct_Float_2_Surf( surf, units, str ) ;

fprintf( fp_o, "surface (%s):%c%s\n", units, Regional_Separator, str ) ;

float vol = Movie_Volume( mov ) ;

if ( (vol < 0.0f) || (vol > 1000000.0f) ) {

fprintf( fp_o, "Volume (%s):%cNot a closed surface\n", units, Regional_Separator ) ;

} else {

Fct_Float_2_Vol( vol, units, str ) ;

fprintf( fp_o, "Volume (%s):%c%s\n", units, Regional_Separator, str ) ;

}
