Floating-point numbers may be specified in any of several common formats making use of the decimal digits, the decimal point \fB.\fR, the characters \fBe\fR or \fBE\fR indicating scientific notation, and -the sign characters \fB+\fR or \fB-\fR. For example, all of the +the sign characters \fB+\fR or \fB\-\fR. For example, all of the following are valid floating-point numbers: 2.1, 3., 6e4, 7.91e+16. Also recognized as floating point values are the strings \fBInf\fR and \fBNaN\fR making use of any case for each character. @@ -256,7 +256,7 @@ All internal computations involving floating-point are done with the C type \fIdouble\fR. When converting a string to floating-point, exponent overflow is detected and results in the \fIdouble\fR value of \fBInf\fR or -\fB-Inf\fR as appropriate. Floating-point overflow and underflow +\fB\-Inf\fR as appropriate. Floating-point overflow and underflow are detected to the degree supported by the hardware, which is generally pretty reliable. .PP |
