ftoi(3)ftoi(3)Name
ftoi, itof, dtoi, itod, gtoi, itog - convert floating values between
VAX and IEEE format
Syntax
int ftoi(value)
float *value;
int itof(value)
float *value;
int dtoi(value)
double *value;
int itod(value)
double *value;
int gtoi(value)
double *value;
int itog(value)
double *value;
Description
The following C library functions convert floating values between VAX
and IEEE formats.
The function converts the specified VAX ffloat number to IEEE single-
precision format. It returns zero if successful and nonzero without
performing the conversion if not successful (for example, underflow).
The function converts the specified IEEE single-precision number to VAX
ffloat format. It returns zero if successful and nonzero without per‐
forming the conversion if not successful (for example, overflow).
The function converts the specified VAX dfloat number to IEEE double-
precision format. It returns zero if successful and nonzero without
performing the conversion if not successful (for example, underflow).
The function converts the specified IEEE double-precision number to VAX
dfloat format. It returns zero if successful and nonzero without per‐
forming the conversion if not successful (for example, underflow or
overflow).
The function converts the specified VAX gfloat number to IEEE double-
precision format. It returns zero if successful and nonzero without
performing the conversion if not successful (for example, underflow).
The function converts the specified IEEE double-precision number to VAX
gfloat format. It returns zero if successful and nonzero without per‐
forming the conversion if not successful (for example, underflow).
