XSLPformatvalue

XSLPformatvalue

Purpose
Format a double-precision value in the style of Xpress NonLinear
Synopsis
int XPRS_CC XSLPformatvalue(double dValue, char *Buffer);
Arguments
dValue 
Double precision value to be formatted.
Buffer 
Character buffer to hold the formatted result. The result will never be more than 15 characters in length including the terminating null character.
Example
The following example formats the powers of 16 from -6 to +6 and prints the results: 
int i;
double Value;
char Buffer[16];

Value = 1;
for (i=0;i<=6;i++) {
  XSLPformatvalue(Value,Buffer);
  printf("\n16^%d = %s",i,Buffer);
  Value = Value * 16;
}
Value = 1.0/16.0;
for (i=1;i<=6;i++) {
  XSLPformatvalue(Value,Buffer);
  printf("\n16^-%d = %s",i,Buffer);
  Value = Value / 16;
}


The results are as follows:
16^0 =  1
16^1 =  16
16^2 =  256
16^3 =  4096
16^4 =  65536
16^5 = 1.048576e+006
16^6 = 1.677722e+007
16^-1 =  0.0625
16^-2 =  0.00390625
16^-3 =  0.00024414063
16^-4 = 1.525879e-005
16^-5 = 9.536743e-007
16^-6 = 5.960464e-008
Further information
Trailing zeroes are removed. The decimal point is removed for integers. Numbers with absolute value less than 1.0e-04 or greater than 1.0e+06 are printed in scientific format.
