| 110 | NAME: |
|---|
| 111 | STRSCI (function) |
|---|
| 112 | |
|---|
| 113 | PURPOSE: |
|---|
| 114 | Given a number, returns a string of that B |
|---|
| 115 | number in scientific notation format ( e.g. A x 10 ) |
|---|
| 116 | |
|---|
| 117 | CATEGORY: |
|---|
| 118 | String Utilities |
|---|
| 119 | |
|---|
| 120 | CALLING SEQUENCE: |
|---|
| 121 | Result = STRSCI( DATA [,keywords] ) |
|---|
| 122 | |
|---|
| 123 | INPUTS: |
|---|
| 124 | DATA -> A floating point or integer number to be |
|---|
| 125 | converted into a power of 10. |
|---|
| 126 | |
|---|
| 127 | KEYWORD PARAMETERS: |
|---|
| 128 | FORMAT -> The format specification used in the string |
|---|
| 129 | conversion for the mantissa (i.e. the |
|---|
| 130 | "A" of "A x 10^B"). Default is '(f12.2)'. |
|---|
| 131 | |
|---|
| 132 | /POT_ONLY -> Will return only the "power of 10" part of the |
|---|
| 133 | string (i.e. the "10^B"). Default is to return |
|---|
| 134 | the entire string (e.g. "A x 10^B" ) |
|---|
| 135 | |
|---|
| 136 | /MANTISSA_ONLY -> return only mantissa of the string |
|---|
| 137 | |
|---|
| 138 | /SHORT -> return 10^0 as '1' and 10^1 as '10' |
|---|
| 139 | |
|---|
| 140 | /TRIM -> don't insert blanks (i.e. return Ax10^B) |
|---|
| 141 | |
|---|
| 142 | OUTPUTS: |
|---|
| 143 | None |
|---|
| 144 | |
|---|
| 145 | SUBROUTINES: |
|---|
| 146 | None |
|---|
| 147 | |
|---|
| 148 | REQUIREMENTS: |
|---|
| 149 | None |
|---|
| 150 | |
|---|
| 151 | NOTES: |
|---|
| 152 | This function does not "evaluate" the format statement thoroughly |
|---|
| 153 | which can result in somewhat quirky strings. Example: |
|---|
| 154 | print,strsci(-9.999) results in -10.0x10^0 instead of -1.0x10^1. |
|---|
| 155 | |
|---|
| 156 | Need a better symbol than the 'x' for the multiplier... |
|---|
| 157 | |
|---|
| 158 | EXAMPLE: |
|---|
| 159 | Result = STRSCI( 2000000, format='(i1)' ) |
|---|
| 160 | print, result |
|---|
| 161 | ; 6 |
|---|
| 162 | ; prints 2 x 10!u6!n, which gets plotted as 2 x 10 |
|---|
| 163 | |
|---|
| 164 | Result = STRSCI( -0.0001 ) |
|---|
| 165 | print, result |
|---|
| 166 | ; 4 |
|---|
| 167 | ; prints -1.00 x 10!u-4!n, which gets plotted as 1.00 x 10 |
|---|
| 168 | |
|---|
| 169 | Result = STRSCI( 0d0, format='(f13.8)' ) |
|---|
| 170 | print, result |
|---|
| 171 | ; |
|---|
| 172 | ; prints, 0.00000000 |

| 175 | MODIFICATION HISTORY: |
|---|
| 176 | bmy, 28 May 1998: VERSION 1.00 B |
|---|
| 177 | - now returns string of the form A x 10 |
|---|
| 178 | mgs, 29 May 1998: |
|---|
| 179 | - bug fix: now allows negative numbers |
|---|
| 180 | - keyword MANTISSA_ONLY added |
|---|
| 181 | - default format changed to f12.2 |
|---|
| 182 | bmy, 02 Jun 1998: |
|---|
| 183 | - renamed to STRSCI ("STRing SCIentific notation"), |
|---|
| 184 | mgs, 03 Jun 1998: |
|---|
| 185 | - added TRIM keyword |
|---|
| 186 | mgs, 22 Sep 1998: |
|---|
| 187 | - added SHORT keyword |
|---|
| 188 | - modified handling of TRIM keyword |
|---|
| 189 | mgs, 24 Sep 1998: |
|---|
| 190 | - bug fix with SHORT flag |
|---|
| 191 | bmy & mgs, 02 Jun 1999: |
|---|
| 192 | - now can handle DATA=0.0 correctly |
|---|
| 193 | - updated comments |
|---|
| 194 | mgs, 03 Jun 1999: |
|---|
| 195 | - can now also handle values lt 1 ;-) |
|---|
| 196 | - and doesn't choke on arrays |
