VMS Help RTL Routines, MTH$, MTH$HSQRT  *Conan The Librarian (sorry for the slow response - running on an old VAX)

    The Square Root (H-Floating Value) routine returns the square
    root of the input value floating-point-input-value as an H-
    floating value.

    Format

      MTH$HSQRT  h-sqrt ,floating-point-input-value

1 - Corresponding JSB Entry Point

      MTH$HSQRT_R8

2 - Returns

    None.

3 - Arguments

 h-sqrt

    OpenVMS usage:floating_point
    type:         H_floating
    access:       write only
    mechanism:    by reference

    Square root of the input value specified by floating-point-input-
    value. The h-sqrt argument is the address of an H-floating number
    that is this square root. MTH$HSQRT writes the address of the
    square root into h-sqrt.

 floating-point-input-value

    OpenVMS usage:floating_point
    type:         H_floating
    access:       read only
    mechanism:    by reference

    Input value. The floating-point-input-value argument is the
    address of a floating-point number that contains this input
    value. For MTH$HSQRT, floating-point-input-value specifies an
    H-floating number.
