.SH "NAME"
frexp \- split a floating point number
.SH "DECLARATION"
.HP \w'genType\ frexp('u
.BI "genType frexp(genType\ " "x" ", out\ genIType\ " "exp" ");"
.HP \w'genDType\ frexp('u
.BI "genDType frexp(genDType\ " "x" ", out\ genIType\ " "exp" ");"
.SH "PARAMETERS"
.PP
\fIx\fR
.RS 4
Specifies the value from which significand and exponent are to be extracted\&.
.RE
.PP
\fIout exp\fR
.RS 4
Specifies the variable into which to place the exponent
.RE
.SH "DESCRIPTION"
.PP
\fBfrexp\fR
extracts
\fIx\fR
into a floating\-point significand in the range [0\&.5, 1\&.0) and in integral exponent of two, such that:
.PP
x = significand ⋅ 2 exponent
.PP
The significand is returned by the function and the exponent is returned in the output parameter
\fIexp\fR\&. For a floating\-point value of zero, the significand and exponent are both zero\&. For a floating\-point value that is an infinity or a floating\-point NaN, the results are undefined\&.
