Fortran - Length of Integer / Number of positions used -


this basic question can't seem find answer on google or through searching though forum (most due poor phraseology of problem).

i looking intrinsic fortran function give me number of positions used integer. mean is, if integer 12543 number of positions used 5 (it positive). reason want when using write statement formatted output can specify "w" in "iw" , use minimum spacing possible.

more specifically:

write(*,"(/ a,iw,1x,a,iw)") "all particles within radius ",radius, "of particle index number", p_o_i

where radius , p_o_i specified user earlier on.

i can write achieve enough thought there must intrinsic function can achieve this.

i have been going through functions here without luck. help.

thanks responses! admit question misleading in requested intrinsic fortran function give number of positions used integer when not strictly required in first place. furthermore, general consensus seems not exist.

as advised francescalus , high performance mark, in order ensure minimum spacing possible used integer, "i0" edit description should used. previous example be:

write(*,"(/ 1x, a, i0, a, i0)") "all particles within radius ",radius, " of particle index number ", p_o_i

should need find number of "characters" in integer (for other reason) best proposed response seems use of log10 function, advised steabert.

javascript - Highcharts multi-color line -

Image
i looking create highchart multi-colored line. if goes down under value, become red, , when comes on value, become green . here picture example: or maybe highcharts have other charts models differentiate high or low level color? you can achieve coloring using lineargradient coloring: color: { lineargradient: { x1: 0, x2: 0, y1: 0, y2: 1 }, stops: [ [0, 'red'], [0.25, 'yellow'], [0.50, 'green'], [0.75, 'yellow'], [1, 'red'] ] } here 0 in stops relates minimum value of series , 1 maximum value, , in between percentages between values. if find percentages according values prior creating chart use correct stops values make relate specific values in data (at least approximately). see this jsfiddle example .
