This COBOL system provides IEEE floating-point support. This is fully compatible with the various languages supplied by Microsoft, including Microsoft Visual C++ V6.0.
Floating-point values must be in the range:
| For COMP-1 data, |
8.43E-37 |
through |
3.37E38 |
| |
-8.43E-37 |
through |
-3.37E38 |
| For COMP-2 data, |
4.19E-307 |
through |
1.67E308 |
| |
-4.19E-307 |
through |
-1.67E308 |
Note that although the above ranges are supported internally, this COBOL system supports only 2 digit exponents, and the range is effectively:
| For COMP-2 data, |
4.19E-99 |
through |
1.67E99 |
| |
-4.19E-99 |
through |
-1.67E99 |
The accuracy of floating-point values is:
| For COMP-1 data (4 bytes) |
6-7 significant digits |
| For COMP-2 data (8 bytes) |
15-16 significant digits |
For literals, floating-point values must be in the range:
- 0.54E-78 through 0.72E+76
- -0.54E-78 through -0.72E+76
